How to protect Facebook from being hacked. To secure your Facebook account, you should consider using the two-factor authentication feature. With the feature enabled, every time someone logs into your account from an unknown device, Facebook asks for a 6-digit dynamic code that must be entered before anyone can log in. The code is sent to your phone number.
