GA4PHP is a class for PHP that allows a coder to provide a method for allowing two-factor authentication for users. Primarily focused on the Google authenticator for iOS, Blackberry, and Android, the system can also support hardware and software tokens based on the TOTP and HOTP standards. The system is designed such that a programmer would simply extend the PHP class to provide storage for the token data.

Release Notes: This first downloadable release includes the base ga4php library, which is fairly functional and stable, as well as an authentication daemon (also written in PHP) that is capable of driving FreeRADIUS. The server component is not yet ready for production and is considered alpha (at best) quality. As yet, it has only been tested on Ubuntu 10.04 32-bit.
