Submission + - Open-source implementation of the Google Auth (dendory.net)
elfguy writes: 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.
