Satellizer makes token-based authentication for your AngularJS app a breeze

Sahat Yalkabov's Satellizer module for AngularJS is an end-to-end, token-based authentication system with built-in support for Google, Facebook, LinkedIn, Twitter, and email/password based authentication.

Satellizer boils the client-side implementation down to adding a module dependency and doing a little configuration, but the server side is still up to you.

Sahat provides server-side examples for popular languages, but plug-and-play server implementations would be awesome and appear to be on the TODO list.
