So, multiple devices, multiple locations.
What if someone’s using your account whilst your out or sending messages as you from a legitimate login? So called ‘frape‘.
Now Facebook tells you where your account is active. Sort of.
Under Account Settings, Security Settings you’ll find one last option, Active Sessions.
Normally there won’t be many as most applications are nice and log you out of a session when you close it. But Browsers and web apps may keep the session alive to make your access simpler, so that you aren’t constantly logging in.
A little reminder of your current connection starts the list.
Then a reasonably informative list of current logged in sessions, including the “Authorised Device” name and a guess at the type of device. Oh, and a really, really approximate location.
To end any suspicious session, just click End Activity and whoosh – it’s gone without any further prompt.
Nice place to just keep an eye on how your account might be being accessed. The time last seen is a useful indicator for the paranoid.
