Facebook is about to unveil a feature that will help you protect your account and manage where you are logged in. The new service which is placed under the heading "Account Activity" in the "Account Security" section of the account settings page will allow you to view all of the active sessions on your Facebook account.
When accessing this, you will also be able to view information about the type of device using your account. The device name, type, and location, as well as when it was last accessed will all come up for your viewing. From there you can quickly and easily end the activity if it is unwanted, or if you forgot to log off.
Facebook also notes how this can be a useful tool in preventing unauthorized people from accessing your account. If there is any suspicious activity, you will be able to simply view what device it is coming from, and if you don't recognize it then you can end the access. Then from there you can precede to reset your password, if you felt that was necessary.
With the privacy woes the social networking giant has come under fire for, it appears that they are now attempting to give you the best security for your account possible. This was first addressed with the new Facebook privacy controls, and now the ability to see where your account is being accessed from will help keep your account safe.
The new feature is slowly but surely rolling out to the user base, and once you have it, you can access it from your account settings under the tab "Account Security."
