I heard of two new authentication schems in ASP+ - Passport authentication and cookie tokens based authentication. Can someone explain in detail the passport authentication scheme? I understand taht the cookie-based authentication is similar to what a lot of people implement on their own now where a custom login page and users/password databases are used except ASP+ does some of the user tracking for us. What about passport authentication. Is there anything related to personalization that ASP+ deals with. I read somewhere that passport authentication supports the storage of userprofiles. Is it similar to cookie based authentication (users/pwd screen etc). Can I accomplish both personalization and users/pwd authentication if i switched to passport authentication? thanks for answering my questions
