FreeOTP

Hello,

I would like to have a FreeOTP compatible authentication (see here: https://fedorahosted.org/freeotp/)

This authentication is very similar to the cookie authentication, except that the informations are stored in an external (mobile) device:

Step 1 - configuration (once):
The application and the mobile exchange a "secret" (through a QR code)

Step 2 - login:
The mobile generate a pin code (ex: 8 chars) and this pin code is entered aside of the login and password.

This system is also used in google two step authentication.

That should be doable. I'm writing the new version of UserSpice that will include OAUTH as well, so I can check out doing that as well. I'd also like to support SQRL, too.
