A couple of weeks ago, google announced a 2-factor authentication system for its marketplace apps (for government and education only, just now)
in their statement Google said : “Two-step verification is built on an open standard designed to allow integration with other vendors’ authentication technologies in the future. We are also open sourcing our mobile authentication app so that companies can customize it as they see fit.”
so i was wondering where is the code for this open source project? yours truly buzzed the question to Ryan Boyd who blogged it at the Google Apps developer blog and he replied with an answer:
the open source project:
http://code.google.com/p/google-authenticator/
It’s based on OATH (unrelated to OAuth):

Thanks Ryan
