OpenID - the "free and easy way to use a single digital identity across the Internet" - has rapidly gained traction as a login credential for Web 2.0 apps and sites. Microsoft Windows Live ID team opened up a Live ID test bed for those developers who want to start playing with Open ID integration. Microsoft has moved to give millions of Windows Live users access to any OpenID-enabled site on the Web by ensuring every Windows Live ID will become an OpenID.

To use:

1. Go to http://login.live-int.com/ and use the Sign up for an account link to set up a Windows Live ID test account in the INT environment.
2. Go to https://login.live-int.com/beta/ManageOpenID.srf to set up your OpenID test alias.

Then:

• Users - At any Web site that supports OpenID 2.0, type openid.live-INT.com in the OpenID login box to sign in to that site by means of your Windows Live ID OpenID alias.
• Library developers - Test your libraries against the Windows Live ID OP endpoint and let us know of any problems you find.
• Web site owners - Test signing in to your site by using a Windows Live ID OpenID alias and let us know of any problems you find.
