Microsoft Opens Up Passport Code
Outside of the Microsoft world, Passport has not made much of a dent.Some people are surprised that Microsoft is opening up the Passport source code, as if the technology had a chance of success without drastic changes. Othersmainly those who work at Microsoftsay Passport has been wildly successful. Passport is integrated into Windows XP, and its required for users to log in to Hotmail and MSNwhich means millions use it every day. Outside of the Microsoft world, however, Passport hasnt made much of a dent, and its supplementary technologies, including HailStorm (.Net My Services), have gone back to the drawing board. Since Passports launch in 1999, Microsoft has worked feverishly to get it right. There are three aspects that Microsoft was working on: to enable Passport to provide single sign-on across Web sites and Web services, to make Passport a credit card wallet, and to make Passport an access control mechanism (for use, among other things, in managing how children interact with the Internet).
Technically, Microsoft did a great job of solving the single-sign-on piece. But outside the Windows world, few are using it, although Passport has made some progress. Its integrated into eBays sign-on page, for example.
