What is Code Generator and how does it work?

Code Generator is a security feature for your Facebook app used with two-factor authentication. When you turn it on, your phone will generate a special security code that you can use to verify it's you when you log in from a new device or browser.
Code Generator works on your mobile device even if you don't have access to text messaging (SMS) or an Internet connection. You can also use it if you ever need to reset your password.
