nodeoauth2

Facebook and Google auth module for NodeJS

NodeOAuth2

Authentication for Facebook and Google using OAuth2. Authenticates the user and returns their access_token and basic user information.

NOTE: Does not provide a session system to provide a drop-in authentication solution. Most other Facebook node modules do this already; this library simply provides a way to authenticate. Session/account management is up to you to implement.

NodeOAuth2 was written with the intention of being used with ExpressJS.
