Facebook has a feature similar to one in Gmail that enables you to see the location from which your account has been accessed, along with the IP address of the computer that was used. This is useful to check for unauthorized access to your account. You may also want to use this function to sign out of sessions if you forgot to do so on a public computer or one that you are no longer using. This information is found under your Account Settings page in your Facebook account. Writer Bio
