Google Friend Connect was a free social networking site, active from 2008 to 2012. Similar to Facebook Platform and MySpaceID, it allowed users to build a profile to share and update information through messaging, photographs and video content via third-party sites which acted as a host for profile sharing and social exchanges. Google Friend Connect used open standards such as OpenID, OAuth and OpenSocial allowing usage with no registration, once authenticated they could use their existing profile and access a social graph when posting messages, the social graph feature allowed a user to post a message on a third-party site, but allowed viewing access only to other authorized "friends" contained within the user's chosen social graph. Google Friend Connect was removed for all non-Blogger sites by March 1, 2012, and for Blogger sites on January 11, 2016.
