What is a One-time Password and how do I use it?
We’ve added One-time Passwords to support applications that do not support Two-Factor Sign In or Facebook/Google+ sign in. The most common use case will be for console games. When you try to log in from a console and forget your password, just hit the Use a one-time password to login link to request a temporary password. Once you receive the email with the password, return to the login screen and enter your email and the password to login. The one-time password expires in approximately 30 minutes, so you will want to use it soon after making the request.
