A single sign-on and digital wallet service from Microsoft that enables users to quickly log in to Windows Live ID-enabled Web sites and identify themselves. Windows Live ID was formerly known as "Microsoft Passport" and ".NET Passport."|
User IDs, passwords, credit card and shipping and billing information are stored on Microsoft servers, which enables users to make purchases without having to retype the information every time. All Microsoft sites use Windows Live ID as well as some third-party sites.
Merchants Query Microsoft's Servers
When users make a purchase on Windows Live ID sites, the merchant sends a request to the Windows Live ID server, which returns the appropriate information. This server-based system supersedes the client-based wallet in earlier versions of Microsoft Internet Explorer. See single sign-on, digital wallet and Liberty Alliance Project.
