Secure the inbox first: it is the key to every password reset.

Quick fix: 6 steps

  1. Locked out? Use accounts.google.com/signin/recovery from a device and place you normally use, and answer every question.
  2. Still in? Open Google Account, Security & sign-in, Review security events and Manage devices.
  3. Change your password to a new, unique one.
  4. Turn on 2-Step Verification (passkey, key or app preferred).
  5. In Gmail, Settings, See all settings, Forwarding: disable forwarding, delete unknown filters.
  6. Change passwords on other sites that use this address. Full cleanup.

Signs your Gmail account has been hacked

If your Gmail account was hacked, you will usually notice it in one of a few ways: you can no longer sign in, your contacts tell you they received strange emails from you, or Google warns you about unusual activity. Google's own help page on compromised accounts lists the patterns worth checking, and it is worth reading them against your own situation before you start changing things, because the fix for "someone is inside my account" is different from the fix for "someone changed my password and locked me out."

These are the signs Google itself describes:

Not every scary email means a breach. A phishing email pretending to be Google ("your account will be closed") is only an attempt. If your sign-in works, your recent security events look normal and nothing in the list above has changed, you were targeted but not compromised. In that case, do not click anything in the message, report it as phishing, and consider turning on stronger sign-in so a future attempt fails. Our phishing explainer shows how to tell the difference.

Quick triage: which situation are you in?

What you seeWhat it usually meansGo to
You can still sign in, but see odd activity or settingsSomeone may have your password, or you left a session open somewhereIf you can still sign in
Password no longer works, recovery phone or email changedAccount taken over and lockedIf you are locked out
Warning email or red bar, but all settings look normalAttempt or blocked sign-inSecurity checkup anyway
Friends get odd links from you, but your sign-in is finePossible stolen password, session or a malicious appAfter you are back in

If you are unsure which row fits, go through the "still signed in" steps first and then the recovery steps. Doing the cleanup in the correct order matters more than doing it fast, and a few minutes of calm triage beats clicking every warning on the screen.

The first 10 minutes: what to do right now

Here is the short order of operations. The sections that follow explain each step with the exact labels Google uses.

  1. Use a device you trust. If you suspect malware on your computer, start from your phone or a friend's clean device. A hacker watching your keyboard will see every new password you type.
  2. Go to Google's account recovery page (accounts.google.com/signin/recovery) if you cannot sign in. If you can, open your Google Account directly at myaccount.google.com.
  3. Review your recent security events and your devices, and mark anything you do not recognize.
  4. Change your password to a new, long, unique one.
  5. Turn on 2-Step Verification, ideally with a passkey, a security key or an authenticator app rather than text messages.
  6. Check Gmail for forwarding rules, filters and delegates that quietly send copies of your mail to someone else.
  7. Change passwords elsewhere for any site that uses this Gmail address or the same password.

The tactics attackers use after getting into Gmail are not random. Your inbox is the key to everything else: password reset emails for your bank, shopping, social media and cloud storage all land there. That is why securing the inbox comes before anything else, and why a changed forwarding rule is one of the most dangerous leftovers of a hack. We come back to that in the settings section below.

One more point on timing. If you saved banking, tax or identity details in your Google Account, or someone may be impersonating you to others, Google advises contacting your bank or the local authorities. In Canada, you can also report fraud to the Canadian Anti-Fraud Centre. Do that after you have secured the account, not instead of securing it.

If you can still sign in: lock it down step by step

Being able to sign in is the best case. Work through the steps below in order. Google's help page for compromised accounts describes the same flow, and the menu labels here come from it, though Google moves buttons around from time to time, so treat the wording as a guide and look for the closest match.

Step 1: Review recent security events

Open your Google Account, go to Security & sign-in, and in the Recent security events panel select Review security events. Go through each entry. If something was not you, select No, it wasn't me and follow the on-screen steps. If everything is yours but you still suspect someone has access, keep going: attackers sometimes sign in from a location or device that looks ordinary.

Step 2: Review your devices

In your Google Account, tap Your devices, then Manage devices. Look for devices you do not own or no longer use. If you find one, select Don't recognize a device? and follow the steps. Old phones, a work laptop you returned, or a tablet you gave away should not be there either. Removing them forces those devices to sign in again.

Step 3: Check Gmail's own activity panel

Open Gmail on a computer at mail.google.com and click Details in the bottom right corner. The "Activity on this account" panel shows whether the account is open in another place, how it was accessed (browser, device, or a mail server through POP or IMAP) and the last 10 IP addresses with approximate locations. It is a good second opinion. Note that Google's page describes it as a viewing tool, not a sign-out tool. For ending sessions on devices, use the device list from Step 2.

Step 4: Change your password

Choose a password that is long and used nowhere else. A passphrase of four or five unrelated words works well, and a password manager makes it easy to keep it unique. Our password manager guide explains how to pick and set one up. Google also tells you to change the passwords of any account that used the same password, that emails you through your Gmail address, where you sign in with that address, or where you saved passwords in your Google Account. Google's Check your passwords option helps find weak or reused ones.

Step 5: Turn on 2-Step Verification

Open myaccount.google.com, tap Security & sign-in, and under "How you sign in to Google" select Turn on 2-Step Verification. Follow the prompts. Google's page lists these second-step options:

If you use a work or school Google account, the steps may not apply and your administrator controls this. After you turn it on, also store the backup codes somewhere safe, offline. For the broader picture see our two-factor authentication setup guide and the passkeys explainer.

Step 6: Check your recovery phone and recovery email

Attackers often swap your recovery phone number or email with their own, so they can get back in later. In Security settings, confirm that your recovery phone, recovery email and any alternate or contact email are yours. Also confirm the 2-Step Verification methods listed are ones you set up. Google lists unfamiliar recovery details and unfamiliar 2-Step Verification methods among its signs of compromise.

Step 7: Remove apps and access you did not approve

Use Review apps with access in your security settings and remove anything unfamiliar. Google also advises turning off less secure app access (View less secure apps), since those sign-in methods skip modern protections. Third-party apps with mailbox access are a common way for spam to keep going out after the password was changed.

The Gmail settings attackers leave behind

This is the step people skip, and it is the one that causes the second hack. Google lists unfamiliar changes to mail delegation, automatic forwarding, scheduled emails, vacation responder, outgoing address, blocked addresses, IMAP/POP access, filters and labels as signs of compromise. A hidden forwarding rule or filter can copy every new email, including password resets, to the attacker even after you changed your password.

Turn off automatic forwarding

  1. On a computer, open Gmail and sign in to the affected account.
  2. In the top right, click Settings, then See all settings.
  3. Open the Forwarding and POP/IMAP tab (or Forwarding).
  4. In the Forwarding section, click Disable forwarding.
  5. At the bottom, click Save Changes.

Review filters, labels and the rest

While you are in See all settings, look through the other tabs for filters that delete, archive or forward mail you did not set up, and delete any you do not recognize. Check the vacation responder, the signature, the "Send mail as" address, blocked addresses and delegated access (Accounts and Import). Google's page on forwarding does not describe a dedicated filters tab, so if the tab names look different on your screen, browse each tab in Settings rather than relying on exact names.

Google's help also says that a filter set to forward messages can trigger a notice in the inbox during the first week after it was created. If you see one you did not create, that is a red flag.

Finally, remove labels you did not create, and check Sent and Trash for messages that show what the attacker did. These may tell you whom the attacker targeted next, which helps when you warn contacts.

Seven mistakes that make a Gmail hack worse

  1. Changing the password from the infected computer. If a keylogger or info-stealing malware is installed, the new password is stolen the moment you type it. Clean the device first, or use another one.
  2. Skipping the forwarding and filter check. Google lists forwarding, filters, delegation and IMAP/POP changes as signs of compromise for a reason. A password change does not remove them.
  3. Turning on 2-Step Verification with only a text message and no backup. Text codes are better than nothing, but Google notes they are more vulnerable to phone number attacks, and losing the phone without backup codes is its own lockout.
  4. Trusting a "recovery service" found through an ad or a comment. Google's help does not mention paid recovery services. Scammers target people who just lost an account.
  5. Ignoring the accounts that depend on Gmail. Your bank, cloud storage and social media may still accept resets to an address an attacker can read.
  6. Deleting evidence. Do not empty Sent or Trash before you have looked at what happened. You may need that for the bank, the police or your own peace of mind.
  7. Never revisiting. Many people fix it once and never check again. Look at Recent security events again after a week and after a month.

Securing Gmail on your phone

Most people read Gmail on a phone, and a phone can hold an open session or a password saved in a browser. After a hack, go through these checks.

If this was a business or Google Workspace account

If you sign in to Gmail through a company address (a Google Workspace account), Google says the standard steps may not work and you must contact your administrator. In a small business that is often the owner or an outside IT provider. Two quick points. First, ask the administrator to review sign-in activity and reset the user's password. Second, look at what the mailbox could reach: customer data, invoices, shared drives. Under Quebec's Law 25 and Canada's federal privacy rules, a breach involving personal information can trigger assessment and notification duties, so write down what happened and when. This is not legal advice: talk to a lawyer or the Commission d'accès à l'information if customer data may have been exposed.

Also warn customers and suppliers about fake invoices or changed bank details sent from your address. Our guide to invoice and vendor fraud explains how that scam works and how to stop it.

What to document

Write down the date you noticed the problem, the symptoms, the suspicious emails, any losses and what you changed. Take screenshots of Recent security events, the device list, and forwarding settings before you change them. If money was taken, give your bank this timeline right away. In Canada you can report fraud to the Canadian Anti-Fraud Centre and to your local police.

How Gmail accounts actually get hacked

Knowing the cause tells you what to fix. In practice, the most common routes are not movie-style hacking but ordinary mistakes and leaks.

CauseHow it looksBest prevention
Reused password leaked elsewhereSign-in from a new place, no phishing involvedUnique password per site, password manager, 2-Step Verification
Phishing page that looks like GoogleYou typed your password after clicking an email linkPasskey or security key (they do not work on fake sites), type the address yourself
Verification code given awayA caller or message asked you to "confirm" a codeNever share codes: Google says it never asks for them by email, phone or message
Malware or info-stealer on your computerSaved passwords and sessions copiedClean device, updates, remove unknown extensions
Malicious app with mailbox accessSpam continues after the password changeReview apps with access, remove unknown ones
SIM swap or text-code interceptionPhone loses service, then the account fallsUse an app, passkey or key instead of text codes, add a carrier PIN

Fake "Google" emails and calls

A big share of Gmail takeovers start with a convincing message: "Your account will be deleted," "Security alert: new sign-in from another country," or "Your storage is full." Some even include a phone number, so you call the scammer yourself. Rules that protect you:

Realistic scenarios

Realistic scenario (illustrative, invented numbers).

Scenario 1: The forwarding rule

Marie runs a small bakery in Laval. A customer says her invoice email looks different. She finds her password was changed, recovers the account in 25 minutes using her usual laptop, but three weeks later her bank reset code is again stolen. The hidden culprit was a forwarding rule she never checked. After disabling forwarding and removing a filter that hid replies, the problem stopped. Lesson: always check Settings after recovery.

Scenario 2: The old password

Daniel sees a sign-in alert from another country. He still has access, changes his password, turns on 2-Step Verification with an authenticator app and reviews devices. An old tablet he sold two years earlier was still signed in. He removes it. Total time: 20 minutes, zero money lost. Lesson: the device list is not decoration.

Scenario 3: Locked out before a trip

Sophie's recovery phone was replaced by the attacker and the password stopped working. She uses the account recovery page from her home computer and her home Wi-Fi, answers every question including her oldest remembered password, and gets back in on the second try. Her first attempt from a hotel computer failed. Lesson: familiar device and place.

What it costs: DIY versus paying a technician

Recovering Gmail yourself costs nothing but time. Google does not charge for account recovery and says it never asks you to pay or to share codes. Count on 20 to 60 minutes for a standard cleanup if you can still sign in, and longer if you are locked out and need several attempts. Optional costs are a password manager (often a few dollars a month, check current pricing), a hardware security key (a one-time purchase, often in the tens of dollars CAD) and antivirus if your computer is infected.

Frequently asked questions

What should I do first if my Gmail account was hacked?
If you can still sign in, open your Google Account, go to Security & sign-in and review security events and devices, change your password and turn on 2-Step Verification. If you cannot sign in, use Google's account recovery page at accounts.google.com/signin/recovery from a device and location you normally use.
How do I know if my Gmail was hacked?
Google lists signs such as missing or unexpected emails, spam sent from your address, changed forwarding, filters or recovery details, unfamiliar apps or devices, unusual sign-in alerts and the red bar reading We've detected suspicious activity in your account. Check Recent security events and the Details link at the bottom right of Gmail.
What if the hacker changed my password and recovery phone?
Use the account recovery page. Google's help says it is meant for exactly this case. Answer every question, use a familiar device, browser and location, enter the most recent password you remember, and use Try another way if the recovery email is out of reach.
How long does Gmail account recovery take?
Google's recovery help page does not state a time limit or a fixed duration, so no one can promise one. If a first attempt fails with the message that Google could not verify the account belongs to you, you can try again with more careful answers and a familiar device.
Can someone read my emails even after I change the password?
Yes, if forwarding, a filter, delegated access or a third-party app with mailbox access was added. Google lists these among the signs of compromise. In Gmail go to Settings, See all settings, Forwarding and POP/IMAP, disable forwarding, and review filters, delegates and Review apps with access.
Should I use text messages for 2-Step Verification?
They are better than nothing, but Google's help notes that text and voice codes are more vulnerable to phone-number-based attacks. Google prompts, passkeys, security keys and authenticator apps are stronger. Keep backup codes stored offline in case you lose your phone.
Will Google call or email me to fix my account?
Google's account recovery help says Google never asks for your password or verification codes by email, phone or message, and that you should only enter them at accounts.google.com. Treat any such request as a scam.
What does the Details link at the bottom of Gmail show?
Gmail's Activity on this account panel shows whether the account is open on other devices or locations, the access type (browser, device or mail server such as POP or IMAP) and the last 10 IP addresses with approximate locations. It is a viewing tool, so use the device list in your Google Account to remove devices.
Is my Gmail hacked if I got a fake Google security alert?
Not necessarily. A fake alert is usually phishing. If your sign-in works and Recent security events looks normal, do not click the message, check your account by opening Google yourself, and report the email. Consider a passkey so a fake page cannot capture your login.
Do I need to change other passwords?
Yes. Google advises changing passwords for any account that used the same password, that emails you through your Gmail address, where you sign in with that address, or whose passwords you saved in your Google Account. Start with banking and other email.
What if I cannot recover my account at all?
Google says you can create a replacement Google Account. You will lose access to the old mail and files, so tell contacts about the new address and update important services as soon as possible.
Can IT Cares recover my Gmail account for me?
No outside technician can recover a Google Account on Google's behalf, and you should avoid anyone who says they can for a fee. We can guide you through Google's official recovery, clean your computer or phone, set up stronger sign-in and check your other accounts. IT Cares is not affiliated with Google.
Does Chrome Password Alert help?
Google's compromised-account guidance suggests turning on Password Alert in Chrome, which warns you when you enter your Google password on a site that is not Google. It is a useful extra layer against fake sign-in pages.
