You, as a Web application developer, are supposed to develop the Web page and authenticate the user by checking the provided user ID and password against some user database

3.PASSPORT AUTHENTICATION
A centralized service provided by Microsoft, offers a single logon point for clients. Unauthenticated users are redirected to the Passport site

4 NONE/CUSTOM AUTHENTICATION:
If we don't want ASP.NET to perform any authentication, we can set the authentication mode to “none”. The reason behind this decision could be: We don't want to authenticate our users, and our Web site is open for all to use. We want to provide our own custom authentication
