Yesterday German email providers Web.de and GMX released a press release stating that their users will be able to log in to Facebook using OpenID (<a href="http://faz-community.faz.net/blogs/netzkonom/archive/2009/08/24/facebook-chooses-german-e-mail-provider-web-de-and-gmx-as-first-open-id-partner-in-europe.aspx" target="_blank">http://faz-community.faz.net/blogs/netzkonom/archive/2009/08/24/facebook-chooses-german-e-mail-provider-web-de-and-gmx-as-first-open-id-partner-in-europe.aspx</a>). Both email providers are subsidiaries of United Internet and dominate the German email market.<div>
<br></div><div>So far both providers offered users a "navigator" to log in to various social networks, online merchants,... However users had to provide usernames and passwords -> password anti-pattern. If I got things right, both providers have to become OpenID Providers now. Though why is there an explicit cooperation with Facebook?</div>
<div><br></div><div>Is Facebook eventually accepting OpenIDs?</div><div>Are Web.de/GMX and Facebook using any vendor specific APIs or extensions?</div><div><br></div><div>Anyone from Facebook here who can shed some light on the topic? Thanks!</div>
