advantages of using passwort authentication:

1. User is not required to learn separate userid and password for every site.
2. User can keep their profile information in a single location.
3. It provides user with sinlge sign-in and stores the information using encryption technologies.
4. The user doesn't have to remember separate user names and passwords for various Web sites and that the user can maintain his or her profile information in a single location. Passport authentication also provides access to other Microsoft services, such as Passport Express Purchase.

Hi James,

Following are a few point on this:

1. The sign-in, sign-out, and registration pages are centrally hosted rather than being specific to each individual site.
2. All .NET Passport sign-in and core profile cookies are strongly encrypted.
3. The central .NET Passport servers return encrypted sign-in and profile information to your site.
4. Members do not need to retype their sign-in name and password when moving from site to site.
5. Participating Web sites never receive a member's password. The authentication cookie is actually a pair of encrypted time stamps asserting when the member signed in.
6. There is no real-time, server-to-server communication between participating Web sites and the central .NET Passport servers.
7. All information exchange occurs through the client's browser using HTTP redirects, encrypted information on the query string, and cookies.
