Google Authenticator Demo


This is a quick demo of how to implement two-factor authentication using the Google Authenticator on your own site or application. I created this page in less than 2 hours to show how trivial it is to do. Here, you can register a user name, and then login by using the information provided by the Google Authenticator. Note that this would also work with any OATH HOTP compliant hardware token.


Enroll

To try it out, simply enter a user name here. It can be anything, made of letters, numbers, dots or the at sign:

User name:


Login

Once you enrolled, enter your user name and the token from the Google Authenticator here:

User name:
Current token:


Reset account

If you ever lose your phone, use the reset key that was provided when you enrolled to reset your account:

Reset key:
