Two factor authentication is a security measure against password theft of your online accounts. It is available for many different online accounts like Facebook, Dropbox, Gmail etc. If you enable two factor authentication for an online account, then you would be sent a code to your mobile phone before you can login to your account. You can also use a configured app to generate these codes on Android or iPhone smartphones. Facebook calls the two step authentication feature with a different name “Login Approvals”. You can add your mobile number to your Facebook account to benefit from the two step authentication and make your Facebook much more secure and hack proof.
