How to find that our facebook account is used by another person

       

        Now a days facebook hacking is becoming a serious issue. We cannot know how it is hacked and who hacked our facebook account. But we can notify when our account is accessed from a computer or mobile device that we haven’t used before. To enable this we have to go to settings->account settings-> now a page will open in that go to security->login notifications->then tick on email and text message boxes and click save changes. Now you will get notification when your account is login by another computer or mobile.
