When you are logged in Facebook Account
1. Check out Login Notification in Security (Settings). We need to make sure that both Email and Text Message are ticked. If its ticked, we can get notification if our account is being accessed from any new device.
2. In same place you can see â€œTrusted Browsersâ€ as second last option. Make sure that there wonâ€™t be more then two. One your computer and another your mobile. If someone happen to know your username and password, even from computers in which you have logged in at some period of time needs to have Facebook code (code send by Facebook) again to logging.
3. At the last you can see â€œWhere Youâ€™re Logged Inâ€. If you have long list in there then you need to remove all and keep only one your mobile and computer. Those are list of device when you have not logged out. End all active session.
As you can see above, its secured only if you are logged in only in two device. One in the computer you are using and another in mobile you use.
I will be updating about more about protection against security threats. If you are aware about the above some points, your profile will be more secured and protected.
