How to Sign Out of Google on All Devices
Old phones, shared computers and unknown sessions can keep access to your Gmail. Here is how to see them all and sign out remotely.
By Siddharth ShankarUpdated October 18, 2026Go to myaccount.google.com, choose Security and sign-in, then Manage all devices under Your devices. Open any device you do not use, have lost or do not recognise and choose Sign out. If you see a device you do not recognise, change your password, run Google’s Security Checkup and turn on two-step verification.
Your email may already be in a known data breach. Find out in about 30 seconds.

Your Google account often stays signed in on old phones, a laptop you sold, a hotel computer or a family member’s tablet. Each one is a door into your email, photos, location history and saved passwords. Google lets you see them all in one place and close the ones you do not need.
How to see every device
1Open your Google Account
Go to myaccount.google.com and sign in.
2Open Security and sign-in
Google’s help page on device access lists this as the first step.
3Choose Manage all devices
You will find it in the Your devices panel.
4Review each device
Select a device or session to see details such as location, time and browser.
How to sign out of a device
Select the device and choose Sign out. Google suggests doing this if a device is lost, no longer yours or does not belong to you. Sessions that are already signed out show a Signed out label.
Do not guess. See which breaches include your email and what leaked.

Is that device really suspicious?
Google lists some details that can look strange but have innocent explanations:
- A device name you do not recognise may be a new, shared or reset device of yours.
- The location may be a nearby place rather than your exact town.
- The time may reflect background syncing rather than when you used it.
- One device can show several sessions, which is normal.
If a browser or place is clearly not yours, treat it as a possible break-in. Google says that to be sure no other device has access, sign out of all sessions with that device name.
If you see a device you do not recognise
1Change your password
Use a strong password you do not use anywhere else.
2Run the Security Checkup
Google’s Security Checkup reviews sign-in methods, recovery options and third-party access.
3Turn on two-step verification
Use an authenticator app, a passkey or a security key if you can.
4Check recovery options and forwarding
Make sure your recovery phone and email are yours, and check Gmail for forwarding rules you did not set up.
5Follow Google’s hacked account steps
Do the same for your other accounts
Most major services have a similar page, often called devices, sessions or where you are logged in. Check your email, social media and shopping accounts, especially after a breach. Read what to do when your email is in a breach and what Google knows about you.
Signing out of Gmail on a shared computer
If you used Gmail on someone else’s computer and forgot to sign out, you do not need the computer back. Use Manage all devices from your own phone or computer, find the session and sign out. Then change your password if anyone else might have seen it.
Remember Android phones and smart TVs
An old Android phone signed in to your Google account can still sync contacts, photos and messages. Smart TVs and streaming boxes with YouTube signed in show up too. Sign out of any you no longer own before you sell or give them away, and factory reset the device as well.
When to check
- After selling, giving away or losing a phone or laptop
- After using a shared or public computer
- After a breakup or when someone else knew your password
- After an alert about a new sign-in
- As a routine every few months
