Facebook login available for Microsoft's Windows 8, Windows Phone 8

Summary: Microsoft and Facebook are making the programming interfaces available to Windows 8 and Windows Phone 8 developers to add Facebook login to their apps.


Microsoft and Facebook are making it possible for Windows Phone 8 and Windows 8 developers to add Facebook Login access to their applications.


Microsoft and Facebook announced on November 14 that developers can get access to the documentation and the application programming interfaces (APIs) through Microsoft's Windows Developer, Windows Phone Developer and Facebook developer sites and blogs.

"Facebook Login for Windows 8 is ready to use in production applications, and for Windows Phone 8, Facebook Login is being launched today as a beta. We expect the beta period to last 60 days or less and encourage developers to try it out and give us feedback," said Microsoft officials in a new blog post.

Facebook Login is meant to be used alongside and/or as an alternative login option to Microsoft Account. It's not designed to replace Microsoft Account logins.

Facebook Login is aimed at helping consumers more easily get "past an identity screen" by being able to tap into Facebook credentials stored on the device. By simplifying sign up and sign in, Microsoft is hoping to get more users to make use of more Windows and Windows Phone apps.

Making use of Facebook Login also allows developers to build into their Windows and Windows Phone apps the ability to share high scores and other app events to Facebook, play games agains Facebook friends and share and access photos inside an app.

Microsoft execs noted that Foursquare and IHeartRadio are going to be using the Facebook Login API on Windows devices, as will Adobe, which is implementing the Facebook Login API on Adobe Revel and Photoshop Express.

  • W8 only

    doesn't work on other versions of Windows, like Windows 7. So, I have no interest.
    • Grow up...

      Do you normally post worthless posts?
    • Ditto on "grow up"

      From his parent's basement, Roteague has spoken!
    • Another Reason

      To get Win 8. ;)
    • I'm with you bro...

      ... ps the cool kids are way over fbook, Redmond locks in another sinker...
  • How safe are proxy logins like this?

    I've been resisting so far using credentials from well-known providers like facebook, gmail, etc. on other sites. My thinking is that I'd rather have unique credentials for each site and store them in my password keeper. I worry that it might be easy to build a spoofing login on some site that doesn't connect securely to facebook, but just captures my facebook login for nefarious purposes.
    So if I use my fb login for many sites, and one app, game, or web app is not legit and captures this login, then all the sites I login to with fb credentials are compromised.
    How can someone tell whether the prompted facebook (or other) login is legit?
    • Not exactly a proxy login...

      The login information is never shared with Windows 8 or WP8. It's only sent directly to Facebook, which replies to the OS that the user can be connected. It's not exactly a proxy style connection as you fear. But rather just a sharing of rights.
      • same concern though

        I understood that Narg, but how will most users know whether the credentials are being sent to Facebook or being skimmed by the app that presents it. It would be trivial to write a spoof facebook login widget that would in fact have nothing to do with facebook, but would just be using the facebook logo.
        • Maybe that is something

          Microsoft can catch when validating the app before releasing it to the store.
          I also have concerns about these apps that want to store all your product keys, etc... Guess I am like you in that case. I can force myself to share with some unknown developer.
    • That's the idea of putting it in the OS

      I'm not going to give my Facebook/Linked-In/Whatever credentials to random AppX. However, I might decide to trust Microsoft (mostly because I know that if Windows ever leaked this information it would end up on the front page of whatever daily newspapers still exist).

      Now I can tell AppX, "use my Facebook credentials, but let the OS handle it for you". AppX never sees anything other that whatever Facebook provides in their API - it may not even see my name or my email address.
  • am nit giing to give my facebook any name.

    As k love it to be.
