You’re sitting there, maybe scrolling through your phone at 11:00 PM, and you see it. A notification from Google or Microsoft saying there’s a "suspicious login" from a city you’ve never visited. Or worse, you try to log in and your password just... doesn't work. Your heart sinks. It’s that cold, prickly feeling in your chest because your entire life is in that inbox—bank statements, private photos, tax returns, and every "Forgot Password" link for every other account you own.
Don't panic. Seriously.

Panic makes you click on "recovery" links that are actually just more phishing traps. Knowing what to do when email hacked is less about technical wizardry and more about a very specific, aggressive checklist of moves to lock the doors before the intruder walks off with your identity. It happens to millions of people every year. Even tech-savvy developers at companies like Cloudflare or Microsoft have been targeted by sophisticated session-hijacking attacks. You aren't "dumb" for getting caught; you're just next on the list.
The Immediate Triage: Getting Back In
If you can still get into your account, you are in a race. The hacker is likely trying to change your recovery phone number or email address right now. If they do that, you're locked out of the house and they’ve changed the deadbolt.
First, change your password. But don't just add a "!" to the end of your old one. Use a completely unique string of random words. A passphrase like Blue-Toaster-Running-High-99 is significantly harder for a brute-force attack to crack than something like Password2024!. While you're in there, look for a setting called "Sign out of all other sessions." Gmail, Outlook, and Yahoo all have this. It’s the "nuclear option." It forces every single device—including the hacker’s laptop—to log out instantly.
What if you're already locked out?
This is where it gets gritty. You have to use the official recovery portal. For Google, it’s account.google.com/signin/recovery. For Microsoft, it’s their account recovery form. Be prepared: they will ask you when you created the account. Most people don't know this. Tip: check your other old email accounts for a "Welcome to Gmail" or "Verification" email from years ago to find that date. If you can't prove who you are, the AI gatekeepers at these companies are notoriously cold. They don't have a customer service line you can just call. You have to prove it through the automated system.

Check Your "Sent" Folder and Forwarding Rules
Hackers are often quieter than you'd think. Sometimes they don't change your password at all. They just want to sit in the corner of your digital room and watch.
One of the sneakiest things they do is set up an email forwarding rule. Honestly, it's brilliant in a localized, evil way. They go into your settings and tell your email to "Forward a copy of every incoming message to [hacker-email]@[suspicious link removed]." You keep using your email like normal, but they see every bank alert and every private conversation. Go to your settings right now. Look for "Forwarding and POP/IMAP." If there’s an email address there you don't recognize, delete it immediately.
Check your "Sent" folder too. Are there hundreds of emails to people you don't know? Hackers love using "clean" accounts (yours) to send out spam or malware because your email address has a good reputation with spam filters. If your friends start texting you saying, "Hey, why did you send me a weird link to a weight loss pill?", you know the damage has already started.
The Domino Effect: Protecting the Perimeter
Your email is the "Master Key." Once someone has it, they can go to Amazon, PayPal, or your bank and click "Forgot Password." Those reset links go straight to the inbox the hacker now controls.
- Call the Bank. Tell them your primary email was compromised. They can put a temporary freeze or a "high-alert" status on your accounts.
- Check your "Deleted Items." Hackers often move bank alerts or password reset emails to the Trash so you don't see them popping up in your inbox.
- The Payroll Pivot. If you use this email for work, tell your HR department. A common scam involves hackers emailing HR from your account to "update" your direct deposit information to a fraudulent prepaid card.
Why 2FA Isn't Always a Magic Shield
We've been told for years that Two-Factor Authentication (2FA) is the silver bullet. It's not. It's great, but it has a massive weakness: Session Hijacking (or Cookie Stealing).
Basically, when you log into your email, your browser saves a "cookie" so you don't have to log in again every five minutes. If you accidentally download a malicious file or click a bad link, a hacker can steal that specific cookie. They don't need your password. They don't need your 2FA code. They just paste that cookie into their own browser and—poof—they are "already logged in" as you.

This is why "what to do when email hacked" has to include a full malware scan of your computer. If you fix the password but the virus is still on your laptop, they'll just steal the new session cookie five minutes later. Use something like Malwarebytes or the built-in Windows Defender to do a deep scan.
The Identity Theft Reality
According to the Identity Theft Resource Center (ITRC), social media and email account takeovers spiked drastically in the last few years. It’s rarely about you specifically. It’s usually about automated scripts finding a hole in your security.
If you suspect your Social Security number or sensitive documents were in your "Drafts" or "Sent" folders, you need to go to IdentityTheft.gov. This is the Federal Trade Commission's (FTC) site. You can create a recovery plan there. It’s a lot of paperwork, but it’s better than finding out three years from now that someone bought a Tesla in your name.
Clean Up the Digital Trail
Once you have control back, it's time to harden the fortress.
- Switch to an Authenticator App. Stop using SMS (text message) codes for 2FA. "SIM Swapping" is a thing where hackers trick your phone carrier into moving your number to their SIM card. Use Google Authenticator, Authy, or Microsoft Authenticator. These apps generate codes locally on your device.
- Revoke Third-Party Apps. Go to your account security settings and look at "Connected Apps." You might see "Random Quiz App" or "Vintage Photo Filter" from 2018. If you don't use it, kill the connection. These are often backdoors.
- Update Your Recovery Info. Is your recovery phone number still that old landline from your parents' house? Change it. Make sure you have "Backup Codes" printed out and hidden in a drawer somewhere.
Moving Forward and Staying Safe
The reality is that once an email is "pwned," it stays on lists sold on the dark web. You can check haveibeenpwned.com to see exactly which data breaches leaked your info. If you see 15 different breaches, it might be time to consider starting a fresh email address for your most sensitive banking and using the old one just for junk mail and shopping.
It's a hassle. Nobody wants to spend their Saturday resetting 40 passwords. But the alternative is a slow-motion wreck of your credit score and personal reputation.
Your Post-Hack Action Plan
- Update your OS. Whether you're on a Mac, PC, iPhone, or Android, run the latest security patches. Vulnerabilities like "zero-day" exploits are patched constantly.
- Audit your secondary accounts. If you used the same password for your email and your Instagram, change the Instagram password now.
- Use a Password Manager. Stop trying to remember 50 passwords. Use Bitwarden, 1Password, or Dashlane. They generate unguessable passwords and keep them behind a master vault.
- Notify your contacts. Send a quick BCC email or post a social media update. "Hey, my email was hacked between 2 PM and 6 PM today. If you got a weird link from me, don't click it." It’s embarrassing, sure, but it’s the right thing to do for your friends' safety.
Getting hacked feels like a violation of privacy because it is. It's a digital home invasion. But by acting fast, cutting off the hacker's access points, and monitoring your financial trail, you can usually stop the damage before it becomes a permanent disaster. Stay vigilant about those "login attempt" notifications; they are often the only warning shot you get.
Immediate Next Steps to Secure Your Identity:
- Check your email forwarding settings right now to ensure no "shadow copies" are being sent to a third party.
- Generate and save "Backup Codes" for your primary email account and store them physically, not digitally.
- Perform a "Security Checkup" within your Google or Microsoft account dashboard to see every device currently logged in and remove any that look suspicious.
- Freeze your credit with the three major bureaus (Equifax, Experian, and TransUnion) if you believe sensitive documents like tax returns or IDs were stored in your inbox.
