Precautions while using Facebook
Create a Facebook Security Question
Youll be sorry you didnt do this if your Facebook account gets hijacked or hacked. The security question not only might help prevent hacks, it also might help restore your account if you do get shut out for any reason. All you have to do is click Edit next to Security Question on your Account Settings Security page, then choose one of the half dozen personal questions Facebook offers. The answer you provide could help Facebook verify your real identity as the account owner if someone hijacks your account.
