Instagram Password Reset Email Bug: What Happened and What You Need to Know [2025]

Understanding the Instagram Password Reset Email Incident

In May 2025, Instagram users worldwide woke up to something unexpected in their inboxes: unsolicited password reset emails. Not just a few. Not just thousands. Millions of users received these emails within a short window, sparking immediate concern about account security and data breaches. According to Forbes, this incident was particularly alarming due to the scale and the fact that the emails originated from Instagram's legitimate systems.

The incident created a perfect storm of confusion. Instagram's initial response was vague. Meta's public statements raised more questions than they answered. Security researchers from organizations like Malwarebytes painted a dramatically different picture than what Meta was telling the public. Users were left wondering: Was my account compromised? Should I change my password immediately? Is my personal information on the dark web?

This wasn't a typical phishing email. These came directly from Instagram's legitimate systems. That made it worse in some ways. Users couldn't dismiss it as a scam. The emails were real. They came from Instagram's actual infrastructure. And they arrived by the millions, as reported by Engadget.

What makes this incident particularly important is how it reveals the gap between what tech companies say publicly and what security researchers actually discover. It's a case study in corporate crisis communication, data security transparency, and the messy reality of managing account security at massive scale.

Let's break down what actually happened, what we know versus what remains unclear, and most importantly, what you should do to protect your Instagram account right now.

TL; DR

The Incident: Millions of Instagram users received unsolicited password reset emails from Meta's systems in May 2025
Meta's Claim: An "external party" triggered the emails, but there was no data breach and user accounts remained secure
Reality Check: Security researchers documented that 17.5 million Instagram user records (including usernames, addresses, phone numbers, and emails) were exposed on the dark web, as detailed by Security Boulevard
The Gap: Meta's "no breach" statement directly contradicted independent security research findings
What You Should Do: Change your password immediately, enable two-factor authentication, and monitor your accounts for suspicious activity
Bigger Picture: This incident highlights the communication disconnect between major tech platforms and security researchers when it comes to data incidents

The Timeline: How the Incident Unfolded

Understanding when things happened helps piece together what actually occurred. The timeline matters because it shows whether Meta knew about certain problems and when.

In the days leading up to the password reset email avalanche, there were no public warnings from Instagram or Meta. No advance notice. No maintenance alerts. Users got no preparation for what was coming.

Then, on a single day in May, the emails started arriving. Not in waves throughout the day, but in concentrated bursts. Thousands of emails per minute were hitting inboxes. Reddit's r/Instagram subreddit exploded with posts. Twitter (now X) became a trending topic. Users were panicking. Some people received multiple reset emails. Others got them repeatedly over several hours.

The volume was staggering. We're talking about enough emails that email servers noticed the spike. Gmail's filtering systems flagged the unusual activity. Yahoo Mail users reported them arriving in strange patterns. It wasn't just Instagram's systems experiencing the problem, it was the entire email infrastructure being impacted by the sheer quantity.

Meta's response came hours after the emails started arriving. No apology. No explanation of root cause. Just a statement that they'd fixed it. The message was essentially: "Don't worry, we handled it, there's no breach."

But within hours, security researchers at Malwarebytes published findings showing that 17.5 million Instagram account records were available on the dark web. These weren't accounts from years ago. These were current, active accounts with recent data.

The timing is crucial here. Were these records exposed due to the same vulnerability that caused the password reset emails? Or were they already compromised and this incident simply revealed what was already lost? Meta hasn't clarified this, which is part of the problem.

What Actually Triggered the Password Reset Emails

This is where Meta's explanation falls apart. According to Instagram's public statement, an "external party" somehow triggered the password reset emails. That's it. That's all they said.

What does "external party" mean exactly? Was it a hacker? A competitor? Someone conducting research? A disgruntled former employee accessing systems remotely? Meta never clarified. The vagueness is almost worse than admitting a breach, because it leaves room for your imagination to fill in the worst-case scenarios.

In technical terms, what likely happened is that someone gained unauthorized access to Instagram's account management systems, or more specifically, the password reset functionality. They probably triggered a mass password reset request programmatically, generating reset emails for a huge list of user accounts.

Password reset systems are typically rate-limited, meaning they're designed to prevent exactly this kind of abuse. If you request a password reset for one account every few seconds, the system should detect this as suspicious activity and block it. But someone either found a way around those protections, or those protections weren't configured properly.

The fact that millions of emails were sent suggests the attacker either:

Had legitimate API access (through a compromised token or stolen credentials)
Found a flaw in the rate-limiting logic that allowed bypassing restrictions
Had access to Instagram's internal systems through a compromised administrator account
Exploited a vulnerability in the password reset endpoint that allowed mass requests

Each scenario is serious. Each one indicates a different kind of security failure. And Meta disclosed almost nothing about which one actually occurred.

Meta's "No Breach" Claim and Why It Matters

Meta's statement was clear and decisive: there was no breach of its systems. User accounts are secure. Everything is fine. Move along, nothing to see here.

But this claim creates a logical problem. If there was no breach, how did 17.5 million Instagram account records end up on the dark web? If user data wasn't compromised, why are usernames, physical addresses, phone numbers, and email addresses now being sold or distributed in the underground internet?

Meta's explanation seems to be that the data was obtained through a separate incident, not connected to the password reset email problem. But they haven't provided evidence of this. They haven't explained when the previous breach occurred or how long user data was exposed.

The distinction matters legally and practically. If Meta suffered a breach, they have obligations under various data protection laws to notify affected users, report to regulators, and take specific corrective actions. If they claim there was no breach, those obligations don't apply.

Security researchers point out that the data exposed is too recent and comprehensive to be from an old breach. The information includes current phone numbers and addresses, updated usernames, and active account information. This suggests the data was harvested relatively recently, not from some incident years ago.

The Malwarebytes Research: What Security Experts Found

Malwarebytes is a legitimate cybersecurity company that researches threats and publishes findings regularly. They're not some fringe operation making wild claims. When they published their findings about 17.5 million Instagram accounts on the dark web, they provided specific details about what information was exposed.

The exposed data included:

Usernames: The actual Instagram handles people use to log in
Physical addresses: Home addresses where users live or have listed in their profiles
Phone numbers: Both mobile and landline numbers linked to accounts
Email addresses: Primary and backup emails associated with accounts
Profile information: Some users' biographical data, relationship status, and other account details

What's particularly alarming is that this data is now available in databases accessible to criminals. Threat actors can use this information to:

Conduct targeted phishing campaigns against specific users
Attempt account takeovers by using the information in password reset requests
Sell the data to other cybercriminals
Use phone numbers and addresses for SIM swapping attacks (more on this later)
Cross-reference the data with other breached databases to find passwords

Malwarebytes didn't just publish a press release. They provided technical analysis, screenshots of the data, and details about where the data was discovered. This level of transparency is exactly what Meta failed to provide.

How This Incident Exposed Security Vulnerabilities

Beyond the immediate problem of millions of password reset emails, this incident revealed several vulnerabilities in Instagram's security infrastructure.

First, the fact that an "external party" could trigger mass password resets indicates insufficient access controls. Password reset functionality should have robust authentication and authorization checks. It shouldn't be possible for an external party to request password resets for millions of accounts unless they either broke in or found a flaw in the system.

Second, there was no circuit breaker or kill switch that stopped the abuse immediately. Modern systems have automated alerts that detect when anomalous activity occurs. If a password reset endpoint suddenly starts receiving thousands of requests per second from unusual sources, the system should detect this and block it. That it didn't (or the blocks weren't triggered quickly enough) suggests those safety mechanisms weren't properly configured.

Third, the fact that user data ended up on the dark web suggests either:

The password reset incident exposed user data directly (through the vulnerable endpoint or systems surrounding it)
A previous, separate breach went undetected for a long time before its effects became visible
User data was obtained through a different vulnerability entirely

Each of these possibilities represents a significant security failure. And Meta still hasn't clarified which one is accurate.

Fourth, Meta's incident response was reactive rather than proactive. They didn't warn users in advance. They didn't provide clear guidance during the incident. They didn't publish a detailed post-mortem afterward explaining what happened and how they're preventing it from happening again.

The Gap Between Corporate Statements and Security Research

This incident perfectly illustrates the disconnect that often exists between what tech companies publicly claim about their security and what independent researchers actually discover.

When Meta says "there was no breach," they're technically correct in a narrowly legalistic sense. They mean their systems weren't permanently compromised and users' passwords weren't stolen directly. But when independent researchers find millions of user records on the dark web, there's clearly a breach of user data somewhere.

This distinction is important but also misleading to regular users. When most people hear "no breach," they think their data is safe. But the exposed data proves otherwise.

The communication gap occurs for several reasons:

First, legal liability. Meta's lawyers are advising them on what they can say without creating legal exposure. Saying "no breach" is safer legally than saying "yes, user data was compromised."

Second, minimizing reputational damage. If Meta admitted to a major breach affecting 17.5 million users, regulators would get involved, lawsuits would be filed, and trust would erode further.

Third, defining "breach" narrowly. Meta might define a breach as unauthorized access to their secured systems. If data was obtained through a different method (like scraping publicly available information or exploiting an unpatched system), they might not count it as a "breach" in their accounting.

Fourth, timing issues. The exposed data might be from an incident that occurred months or years ago but only became visible to security researchers recently. Meta might not even know when or how the original compromise occurred.

Regardless of the reasons, this gap creates a trust problem. Users can't rely on company statements to understand whether their data is secure. They have to wait for independent researchers to publish findings.

How to Protect Your Instagram Account Right Now

Whether or not you were directly affected by this incident, now is the time to strengthen your Instagram security. Assume that your information is at risk and take protective measures.

Step 1: Change Your Password Immediately

Create a new password that's unique to Instagram and different from all your other passwords. Use a mix of uppercase letters, lowercase letters, numbers, and special characters. Make it at least 16 characters long if Instagram allows it.

Don't use a password that you've used on any other website. If Instagram is compromised in the future, hackers will try using the same password on your email, banking, and other critical accounts.

Step 2: Enable Two-Factor Authentication (2FA)

Go to Settings > Security > Two-Factor Authentication. Instagram offers several options:

Authentication app (most secure): Use Google Authenticator, Microsoft Authenticator, or Authy
SMS text message: Less secure than an authentication app, but better than nothing
Backup codes: Generate one-time codes you can use if you lose access to your phone

Authentication apps are more secure than SMS because hackers can't intercept codes with a SIM swap attack (at least not easily).

Step 3: Review Active Sessions and Connected Apps

Go to Settings > Security > Logins. Review all devices and locations currently logged into your account. If you see any logins from places you don't recognize or on devices you don't own, click the three dots next to them and select "Log Out."

Also check Settings > Apps and Websites to see which third-party applications have access to your Instagram account. Revoke access from anything you don't actively use.

Step 4: Check Your Recovery Options

Make sure your account recovery email and phone number are current. If you use an old email address as your backup recovery method and that email is compromised, hackers could use it to reset your Instagram password.

Go to Settings > Account > Personal Information and verify that your email and phone number are up to date.

Step 5: Monitor for Suspicious Activity

Set up login alerts so Instagram notifies you whenever someone logs into your account from a new device or location. You should receive alerts for every single login that isn't from your regular devices.

Also monitor your linked email address and phone number for any suspicious activity. Check if you're receiving unexpected emails or texts from Instagram or other services.

Step 6: Secure Your Email Account

Your email is the master key to all your accounts. If someone gains access to your email, they can reset passwords for Instagram, banking, cryptocurrency wallets, and everything else.

Enable two-factor authentication on your email account using an authentication app (not SMS). Use a strong, unique password. Review your email's security settings and recovery options.

Understanding Account Takeover Attacks and How They Work

The exposed user data from this incident puts accounts at risk for takeover attacks. Understanding how these attacks work helps you defend against them.

A typical account takeover attack works like this: A hacker obtains your username and email address (like from the leaked Instagram data). They visit Instagram's login page and enter your username. Then they click "Forgot Password." Instagram sends a password reset email to your email address.

But the hacker doesn't have access to your email. So how do they get in?

If your email address is also compromised in another breach, they might already have your email password. They log into your email, find the Instagram password reset email, click the reset link, and create a new password. Now they control your Instagram account.

Alternatively, if your phone number is associated with your account and it's one of the exposed numbers from this incident, a hacker can attempt a SIM swap attack. They call your mobile carrier, pretend to be you, and claim they lost their SIM card. If they can convince the carrier to transfer your phone number to a new SIM card under their control, they receive all your two-factor authentication codes.

This is why the exposed information is so dangerous. It provides hackers with everything they need to launch targeted takeover attacks against specific users.

The Broader Context: Why These Incidents Keep Happening

This Instagram incident isn't unique. It's part of a pattern of security incidents affecting major social platforms. Understanding the broader context helps you understand why these incidents occur and how to respond.

Social platforms like Instagram face unique security challenges:

Scale: Instagram has over 2 billion monthly active users. Managing security at that scale is incredibly difficult. With that many accounts, even a 0.001% vulnerability affects thousands of users.

Complexity: The underlying systems that power Instagram are extraordinarily complex. They involve multiple services, databases, APIs, and integrations. More systems means more potential attack surface.

Legacy code: Instagram was founded in 2010 and acquired by Facebook (now Meta) in 2012. Parts of the platform probably run on code that's over a decade old, potentially with security assumptions that are outdated.

API access: Instagram provides APIs for third-party developers and advertisers. These APIs require authentication and authorization. If those systems are misconfigured or vulnerable, attackers can exploit them.

Data centralization: All user data is stored in Meta's databases. If those databases are breached, the impact affects millions of people simultaneously.

Underground market demand: Hacker forums actively buy and sell Instagram accounts and data. This creates financial incentive for attackers to target the platform.

Companies invest billions in security, but attackers only need to find one vulnerability. The asymmetry of security makes incidents like this inevitable.

What Regulators and Lawmakers Are Doing

In response to incidents like this and broader privacy concerns, regulators worldwide are implementing stricter requirements for tech companies.

In the European Union, the General Data Protection Regulation (GDPR) requires companies to notify regulators and affected users within 72 hours of discovering a data breach. The penalties for non-compliance are severe, up to 4% of annual revenue.

The U.S. doesn't have a unified federal privacy law yet, but individual states are implementing their own requirements. California's Consumer Privacy Act (CCPA), Virginia's Consumer Data Protection Act (VCDPA), and similar laws in other states all impose requirements on how companies handle user data and report breaches.

For this Instagram incident, Meta likely has obligations to notify regulators and potentially affected users in various jurisdictions, even though they claim there was no breach.

Lawmakers are also pushing for stronger requirements around account security. Some proposals would require companies to make two-factor authentication mandatory for certain users (like government accounts or high-value accounts), not optional.

This Instagram incident wasn't the first security problem involving major social platforms, and it probably won't be the last.

In 2021, Facebook experienced a major outage affecting billions of users worldwide for several hours. The outage was due to misconfiguration of their routers, not a security attack, but it demonstrated how fragile even giant tech companies' infrastructure can be.

In 2023, Twitter (now X) experienced security issues with its API that exposed user data. Elon Musk's rapid changes to Twitter's security infrastructure and staff reductions made it harder to maintain security standards.

TikTok has faced repeated investigations and concerns about data security and privacy, particularly regarding whether user data is accessible to the Chinese government.

Snapchat has experienced multiple data breaches over the years, exposing user information including phone numbers and usernames.

Comparing these incidents reveals a pattern: social platforms are regularly targeted by attackers because of the value of user data. And they regularly fail to prevent compromises or communicate transparently about them.

Technical Deep Dive: How Password Reset Systems Should Work

Understanding how password reset systems are supposed to work helps explain why this incident was a vulnerability.

A proper password reset system has several components:

Authentication: The system verifies that the request is legitimate. This typically involves checking that the person requesting the reset has access to the email address or phone number associated with the account.

Rate limiting: The system restricts how many password resets can be requested per account per time period (e.g., 3 resets per hour per account). This prevents someone from flooding an account with reset requests.

Anomaly detection: The system monitors for unusual patterns. If password reset requests suddenly spike or come from unusual geographic locations, the system detects this and may trigger additional verification steps.

Token expiration: The reset tokens sent in emails expire after a short period (typically 1 hour). This prevents someone from using an old token to reset a password days or weeks later.

Confirmation: The system requires users to confirm their reset by clicking a link in an email or entering a code. This ensures only people with access to the registered email can reset the password.

Logging: The system keeps detailed logs of all password reset requests, including timestamp, IP address, and user agent. This allows security teams to investigate incidents afterward.

When Instagram's system allowed millions of password resets to be triggered, at least one of these components failed. It could have been missing rate limiting, broken anomaly detection, insufficient authentication on the reset endpoint, or something else entirely.

The Role of Security Researchers and Bug Bounties

This incident highlights why independent security researchers are crucial for tech platforms.

Most major tech companies, including Meta, operate bug bounty programs. They pay researchers who discover vulnerabilities to report them privately instead of publishing them publicly. Facebook's bug bounty program has paid out millions of dollars in total.

But bug bounties work best for researchers who can identify vulnerabilities before they're exploited. They don't help catch vulnerabilities that are already being exploited by criminals.

Malwarebytes and other independent security firms operate by monitoring the dark web, analyzing attack tools, and researching new threats. They're not bound by corporate incentives to minimize problems. They publish findings publicly, which creates pressure on companies to take them seriously.

This is why Meta's silence about the actual scope of the incident is frustrating. Independent researchers have filled the information vacuum with their own findings, and those findings contradict Meta's claims.

If Meta had published a thorough incident report immediately after the incident was fixed, explaining exactly what happened, how much user data was exposed, and what they're doing to prevent future incidents, the story would be different.

Lessons for Users and Companies

This incident provides several lessons for both individual users and companies building social platforms.

For users:

Don't trust companies' claims about security incidents at face value. Wait for independent researchers to publish findings.
Assume your personal information is already compromised somewhere. Protect yourself accordingly by using unique passwords and two-factor authentication everywhere.
Monitor your accounts actively. Set up alerts for logins. Review connected apps regularly. Don't assume security issues will be fixed before you're exploited.
Prioritize security on your email account. It's the master key to everything else.

For companies:

Transparency is better than opacity. Companies that communicate clearly about security incidents inspire more trust than companies that minimize or hide problems.
Incident response speed matters. Hours of delay allow attackers to exploit vulnerabilities longer and affects more users.
Security isn't optional. Companies that view security as a cost center rather than a core capability will continue experiencing incidents.
Rate limiting, anomaly detection, and access controls should be implemented at multiple layers. Defense in depth catches vulnerabilities that single controls miss.

Looking forward, we can expect several trends in social media security:

Mandatory 2FA: Regulators are likely to require two-factor authentication for all accounts, not just optional for security-conscious users.

Decentralization: Some users are migrating to decentralized social networks that don't store all data in a central database controlled by one company. This reduces the impact of any single breach.

Zero-knowledge architecture: Platforms are moving toward storing data in ways that even the company can't access it without user consent. This protects user data even if the company is hacked.

Blockchain integration: Some platforms are exploring blockchain-based authentication and identity verification, though this technology has its own limitations and challenges.

Regulatory enforcement: As laws like GDPR and state privacy laws are enforced more strictly, companies will face real consequences for security failures. This will drive investment in security.

FAQ

What exactly triggered the Instagram password reset emails?

An external party gained unauthorized access to Instagram's password reset system, allowing them to trigger mass password reset requests for millions of accounts. Meta hasn't provided details about how the access was obtained, whether through compromised credentials, an exploited vulnerability, or another method. The incident revealed that Instagram's system lacked sufficient safeguards to prevent this kind of abuse.

Should I be worried if I received one of these password reset emails?

Yes, you should treat it as a warning sign that your account may be at risk. While the password reset email itself isn't dangerous (clicking the link won't cause any damage), it indicates that your account was targeted. You should immediately change your password to something unique and complex, and enable two-factor authentication if you haven't already. Monitor your account for any unauthorized changes to your email address, phone number, or recovery options.

Did Meta confirm that a breach occurred?

Meta officially stated that there was no breach of its systems. However, independent security researchers from Malwarebytes found 17.5 million Instagram user records (including usernames, addresses, phone numbers, and emails) available on the dark web. This contradiction is confusing, but the most likely explanation is that Meta is using a narrow definition of "breach" (unauthorized access to secured systems) while the exposed user data was obtained through a different method. Regardless of the terminology, user data is clearly exposed and at risk.

How can attackers use the exposed information (usernames, addresses, phone numbers) to compromise my account?

Attackers can use this information to conduct targeted attacks. With your username and email address, they can request a password reset. If they've also compromised your email account (from another breach), they can access the reset email and change your password. Alternatively, if they have your phone number, they may attempt a SIM swap attack, convincing your mobile carrier to transfer your number to a new SIM card under their control. With your number, they can receive two-factor authentication codes.

What's the difference between a data breach and exposed user data, and why does Meta's distinction matter?

Meta defines a data breach as unauthorized access to their secured systems. If user data was obtained through a different method (like scraping publicly available information, exploiting an unpatched system that wasn't part of their core security infrastructure, or a third party obtaining data from another source), Meta wouldn't classify it as a breach. This distinction matters legally because breach notifications and regulatory reporting requirements only apply to certain types of incidents. For users, the distinction matters less; what matters is whether their personal information is exposed and at risk.

How long does it typically take for exposed data to appear on the dark web after a breach occurs?

There's significant variation. Some data appears on the dark web within days of being compromised. Other data sits in underground marketplaces for months or years before becoming visible to security researchers. The Instagram data that appeared in this incident could have been compromised recently, or it could have been obtained and stored for a long time before being publicly listed. Meta hasn't clarified the timeline.

Are my old Instagram messages at risk if my account is compromised?

Not directly. If someone gains control of your Instagram account, they can't read your old direct messages unless Instagram stores decrypted copies of those messages on their servers. However, they could read new messages that come in while they control the account. They could also change your privacy settings, making your profile public or changing your contact information, which could lead to other problems.

Should I delete my Instagram account after this incident?

That's a personal decision. Deleting your account won't protect data that's already been exposed, since it's already been compromised and distributed. However, deleting your account does prevent future exposure if there are additional vulnerabilities. Most security experts recommend staying on the platform but hardening your security through strong passwords, two-factor authentication, and regular monitoring. The inconvenience of deleting your account usually outweighs the security benefit.

What should I do if I notice suspicious activity on my Instagram account after this incident?

Immediately change your password from a trusted device. If you can't access your account, use Instagram's account recovery process. Contact Instagram's support team through the app or website (not through email links, as those could be phishing attempts). Check if your email or phone number has been changed. Enable two-factor authentication if you haven't already. If you suspect financial fraud or identity theft beyond Instagram, contact your bank and consider filing a report with the Federal Trade Commission (FTC) at Identity Theft.gov.

Will Meta face any legal consequences for this incident?

Possibly. Regulators in various jurisdictions may investigate whether Meta complied with data breach notification laws. The EU's GDPR requires notification within 72 hours of discovering a breach. Various state privacy laws in the U.S. also impose notification requirements. Additionally, users may file class-action lawsuits seeking damages. Meta's response so far (claiming no breach) might complicate this, since if regulators ultimately determine that a breach did occur, Meta could face penalties for delayed notification.

What's the long-term impact of this incident on Instagram's reputation?

This incident adds to existing concerns about Meta's commitment to user privacy and security. Investors might reduce their confidence in Meta's ability to manage security risks. New users might choose competing platforms like BeReal or TikTok. Existing users might reduce their personal information sharing or migrate to alternative social networks. The impact depends on how Meta responds going forward—if they publish a detailed incident report and make significant security improvements, the damage might be limited. If they continue to minimize the incident and avoid transparency, the damage could be more severe.

What This Means for Your Digital Security Going Forward

The Instagram password reset incident isn't an isolated problem. It's symptomatic of broader challenges in digital security and corporate transparency.

Your personal data is increasingly valuable to criminals. Every company you trust stores some of that data. Every company is a potential target. And incidents like this one reveal that even the most sophisticated companies with billions of dollars for security can fail to prevent attacks.

You can't control whether companies secure your data properly. But you can control how you respond when incidents occur. You can assume that your personal information is compromised somewhere. You can use unique passwords everywhere. You can enable two-factor authentication on critical accounts. You can monitor your accounts for suspicious activity. You can prioritize the security of your email account above all others.

Most importantly, you can stop trusting company statements about security at face value. Wait for independent researchers to publish findings. Check breach databases. Ask critical questions. Demand transparency from companies that hold your personal information.

The Instagram incident is a reminder that privacy and security aren't guaranteed by companies' promises. They're earned through your vigilance and your willingness to hold companies accountable.

For companies like Meta, the lesson should be clear: transparency works better than minimization. Users and regulators will eventually learn the truth. It's better to acknowledge problems honestly, explain how you're fixing them, and take concrete steps to prevent future incidents.

Until tech companies prioritize transparency about security incidents the way they prioritize product launches, you should assume that your data is at risk and take personal responsibility for protecting your accounts.

Start today. Change your Instagram password. Enable two-factor authentication. Review your account recovery options. Monitor for suspicious activity. Don't wait for the next incident to take these steps. The time to secure your account is before you need to.
