    The ASP.NET Framework supports three types of authentication:
    • Windows Authentication
    • NET Passport Authentication
    • Forms Authentication

    Windows authentication
    It is enabled by default. When Windows authentication is enabled, users are identified by their Microsoft Windows account names.
    .NET Passport authentication
    It is a centralized service provided by Microsoft. .NET Passport allows users to create a single sign-in name and password to access any site that is uses .NET Passport authentication
    Passport simply tells a participating site who the user is. MSN and Hotmail uses .NET Passport authentication.
    Forms authentication
    In this authentication users are typically identified by a cookie. When a user is authenticated, an encrypted cookie is added to the user’s browser. As the user moves from page to page, the user is identified by the cookie.
