OAuth

“While OpenID is all about using a single identity to sign into many sites, OAuth is about giving access to your stuff without sharing your identity at all.”Eran Hammer-Lahav

OAuth (Open Authorization) is an open standard for token-based authentication and authorization on the Internet.

There’s a lot of buzz about how OAuth is making it possible for end users to move from website to website without having to expose passwords — the authentication part — but the really powerful part of OAuth is that its access tokens specify what data can be accessed — the authorization part.
