Does Facebook alert you when someone tries to log into your account?
If someone does try to get into your account Facebook will immediately notify you of the attempt and will lock your account. With your account locked Facebook will ask you to review the login attempt. Someone recently tried to log in to your account from an unrecognized device or mobile device.
How do you unlock another Facebook account?
In place of the Lock Profile option, you will now see an Unlock Profile option, tap on it and hit Unlock on the next screen. You will see a brief on how unlocking your profile works and an option to Unlock Your Profile at the bottom, click on it and your profile will be unlocked.
