Facebook Connect, also called Log in with Facebook, like OpenID, is a set of authentication APIs from Facebook that enable Facebook members to log onto third-party websites, applications, mobile devices and gaming systems with their Facebook identity. While logged in, users can connect with friends via these media and post information and updates to their Facebook profile. Developers can use these services to help their users connect and share with their Facebook friends on and off of Facebook and increase engagement for their website or application.
Originally unveiled during Facebook’s developer conference, F8, in July 2008, Log in with Facebook became generally available in December 2008. According to an article from The New York Times, “Some say the services are representative of surprising new thinking in Silicon Valley. Instead of trying to hoard information about their users, the Internet companies (including Facebook, Google, MySpace and Twitter) all share at least some of that data so people do not have to enter the same identifying information again and again on different sites.”
