Microsoft on Tuesday expanded the capabilities of its Windows Live ID service by adding support for single sign-on for its Windows Live services and making it possible for users to sign up for an ID from a mobile device. Microsoft executives posted the updates to Windows Live on separate blog entries. Windows Live ID is the gateway to Microsoft"s Windows Live services, which include e-mail, instant messaging, blog hosting, and security.
Users with multiple sign-ons for various Windows Live services can now unify them through one ID and password, according to a blog entry from Jeff Steinbok, a member of Microsoft"s Live Spaces development team (sign-in required). To set this up, users can go to the Windows Live account site and look for the section called Linked Windows Live IDs. A user can add IDs to a single "linked" ID and password so that they need to sign in only once to use various Windows Live services.
