Windows CardSpace

The Internet continues to be increasingly valuable, and yet also faces significant challenges. Online identity theft, fraud, and privacy concerns are rising. Users must track a growing number of accounts and passwords. This burden results in "password fatigue," and that results in insecure practices, such as reusing the same account names and passwords at many sites. Many of these problems are rooted in the lack of a widely adopted identity solution for the Internet.

CardSpace is Microsoft's implementation of an Identity Metasystem that enables users to choose from a portfolio of identities that belong to them and use them in contexts where they are accepted, independent of the underlying identity systems where the identities originate and are used.
