Sign Out of Gmail on Multiple Devices

In 2016, Gmail had more than 1-Billion active users every month. If you are one of those 1-Billion users of Gmail, and if you check your e-mail on more than one computer, it is possible that your Gmail account is still signed in on a computer that you don't control.

Do you check your Gmail from work? Did you remember to sign out after you logged into your Gmail at school, the library, at the hotel during your last business trip or vacation? More importantly, if a laptop or mobile device is lost or stolen, it’s crucial to know how to disconnect your private accounts from it immediately.

To sign out of Gmail on multiple devices:

1. Log in to Gmail on your computer.
2. Scroll to the bottom of your inbox.
3. There in the lower right corner, below your e-mail you will see, in small print, "Last account activity".
4. Click the "Details" link below the last account activity date/time.
5. Here you will see an activity log showing when an where your Gmail account has been logged-in.
6. On the details page, click the "sign out all other web sessions" button to remotely log out of Gmail from computers in other locations. 

If someone has your password, or if you have it saved on the computer, that person could log back into your Gmail account. So, it is a good idea to change your password if you see any log-ins that you didn't make, or if you think your password might have been saved to a computer other than your own.
