Keith Brown has an article on MSDN that’s a step-by-step guide for using InfoCard. InfoCard seems like it’ll be really nice. However, identity management has never been a strong suit for Microsoft, so I’m cautiously optimistic, at best. I wish it wasn’t being tied so closely with the train wreck Microsoft is calling Vista. More and more that seems like it might be a rather large albatross being tied around InfoCard’s neck.
Anyway, here’s a little of what Keith has to say about InfoCard:
InfoCard is not the "Son of Passport" that some in the media seem to fear. Passport is a single identity system and, as such, naturally fits into the metasystem as one of many technologies available to InfoCard users. But unlike the old days when Passport was being positioned as the only identity system you’d ever need on the Internet, today Microsoft is proposing a metasystem that allows the user to choose the identity technologies that make sense for her. Passport works well for accessing Microsoft properties like MSN®, but as an InfoCard user, that’s the only context in which I’ll be using Passport. My friends will tell you that I was never a big fan of Passport, but I am really excited about InfoCard, and you should be too!
