If you’re constantly forgetting to log out of Facebook when you use other people’s computers or phones, Facebook’s new remote logout feature is right up your alley. Under Account Settings (specifically, the Account Security section), you can now see a list of places where you’re currently logged in, along with some info to help you determine whether each session is legitimate or unauthorized. And, of course, you also have the option to log any of those sessions out.
Based on the approximate location (determined via IP address), the time the session started, and the browser and OS, you should be able to tell whether you just forgot to log out at work, or whether someone else has accessed your account. You can also sign up to be alerted via email or text when someone tries to log in from a device that you haven’t registered with Facebook.
The service isn’t available for everyone yet, but it’s rolling out now, and it should reach you soon if you don’t already have it.
Now that is a feature I can admire.
