Sessions

Sessions lists every device currently logged into your account: its IP address, whether it's the device you're using right now (the This Device? column), its user agent, and when it was last active.

Revoking a Session

Right-click a session (or open the menu at the end of its row) and select Remove to log it out; on your current session the action is disabled. This is useful if you spot a session you don't recognize or want to sign out an old device.
