Microsoft has released a pair of Windows Live SDKs that it says can manage the process of authenticating users of Web or client apps for developers, while sparing them from the headache of creating and storing thousands of user accounts. The Live ID system also allows any of the hundreds of millions of people with a Windows Live account, primarily Hotmail users, to sign in to a Live ID-enabled Web service or client app without having to get a new user name or password specific to that service or app, the company says.
he Windows Live ID Web Authentication and Windows Live ID Client Authentication SDKs are aimed at developers. Microsoft's CardSpace, an information card technology that ships with Windows Vista and can be downloaded for XP, similarly allows end users to manage their various online identities.
