Extended Authentication (XAuth) makes social sharing easier by automating the way users share the content on various social networks. XAuth was an initiative by Meebo. When you log in to social networks like Google, Microsoft, MySpace, Yahoo! and others, these services notify xAuth.org that you have an active session with the service. When you visit a website, which is xAuth enabled, XAuth will ping all the partipating social networks to see if your session is still active. If any of these services are being used, you can authenticate directly from the publisher’s website and share the content to your social network. It is similar to Facebook Connect, but it is meant for every social network.
