Microsoft Windows Live service will also become an OpenID provider, this was revealed by the company on Monday. With this announcement you’ll soon be able to use your Windows Live account to sign into any site on the web that supports OpenID. Windows Live ID login is what you are currently using to sign on to Hotmail, MSN Messenger, Spaces or any of Microsoft’s Live services.
The Windows Live ID OpenID Provider (OP) enables anyone with a Windows Live ID account to set up an OpenID alias and to use that alias for identification at an increasing number of OpenID 2.0 relying party sites-for example: Plaxo, Technorati and Wikispaces.
This service is not available now but for public testing right now and the official release will be in 2009. This announcement was made by Kim Cameron the PDC developer event in Los Angeles. Cameron is the Chief Architect of Identity in Microsoft’s Connected Systems Division.
Open Id has already gained momentum and I feel its very late for big players like microsoft. I feel Open ID should be made a standard or everyone should implement .tel names
