Auto Logout is a Facebook and Twitter utility that automatically logs you out from the site after 10 minutes. Once you install this program, it will automatically log you out from Facebook, Twitter, and Quora once it detects that you have been inactive for a certain period of time. This means that you don't have to keep checking to see if you are still logged in. 

In other words, the Auto Logout app will automatically log you out after 10 minutes. If you have a Facebook account, you will be logged out automatically if you haven't interacted with the site for a certain time period.
