Wherever the Internet goes, there goes Gmail. A phone, a relative's desktop computer, a stranger's laptop: with but your user name and password, you can access your Inbox.
Now, about that stranger's laptop on the train. Did I sign out of my Gmail account when I handed it back? I think I did, but what about aunt Amalia's desktop (and her nephews)?
Fortunately, Gmail lets me and you sign out remotely — making sure any attempt to open or send an email in on one of the leftover sessions is met with but a log-in page and the need for a password.
Sign Out of Gmail Remotely
To make Gmail sign you out of all sessions that may be open on other computers and devices:
- Click Details under Last account activity at the bottom of Gmail.
- Now click Sign out all other sessions.
This will disable any future action in all other Gmail sessions. Note that
- the open sessions may still display your Inbox or a message that will only disappear when some action, say opening a conversation, is performed; and that
- other users may be able to log back into Gmail if your user name and password are stored in the browser. If you suspect that, make sure you change your password.
