How to remotely sign out of your account.

If you have used Facebook at the library or a friend’s computer and forgot to log out, then you may be relieved that there is a way to sign out of your account remotely.  You can do this by going to your “Account Settings” and then “Security.” At the bottom of the page, you will notice a section called “Active Sessions.”  When you hit “End All Activity,” Facebook will log out your account from every computer and mobile device that you have an active session in.  You can also log out of each specific computer or mobile device instead of ending all of your sessions.
