Legacy Update: Get back online, activate, and install updates on your legacy Windows PC

Introducing an easy way to integrate the Windows Live ID authentication service into your Web site!

Important Web Authentication is designed for use only by sites that are not affiliated with Microsoft. If your site is associated with Microsoft, please contact the Windows Live ID team to determine the proper implementation.

The Windows Live ID Web Authentication SDK describes a platform-independent interface for implementing Windows Live ID sign-in on Web sites of all kinds. This release includes a sample application for each of seven different programming languages: ASP.NET (C# and VB), Java, Perl, PHP, Python, and Ruby. For each language there is a function library that you can use to extend the sample.

The SDK consists of the samples and libraries available on this page together with the SDK documentation. For a link to the documentation on MSDN®, see Related Resources later on this page.

Use of the SDK is governed by the Windows Live SDK License Agreement at: http://msdn2.microsoft.com/en-us/library/bb226715.aspx

Benefits

• The ability to use Windows Live gadgets and controls to incorporate authenticated Windows Live services into your site.
  
• An HTTP-based, platform-neutral interface for implementing Windows Live ID authentication in your existing site, even if it is hosted by a third-party.
