Facebook Device Notifications for Account Security
I was playing around with my Facebook settings today and I found a great new feature called Account Security under Account Settings. This new and unknown Facebook feature provides a way to monitor your account logins from any Computers or Mobile Devices.
Facebook Account Security
This feature works by Registering every Computer or Mobile Device when you use for the first time. Facebook knows your devices by saving a Cookie inside your browser so when you login again, Facebook will know this is your Computer.
In case someone stolen your credentials (Username & Password) or your one of those 1.5 Million hacked Facebook accounts, you will receive an E-Mail stating the following:
As the E-Mail is stating, Facebook keeps a record of all your registered Computer & Devices which are assigned to your account.

My advice: Enable this feature ASAP
