Windows:
Specifies Windows authentication as the default authentication mode. Use it with any form of Microsoft Internet Information Services (IIS) authentication: Basic, Digest, Integrated Windows authentication (NTLM/Kerberos), or certificates. In this case, your application delegates the authentication responsibility to the underlying IIS.
Forms:
Specifies ASP.NET forms–based authentication as the default authentication mode.
Passport:
Specifies Microsoft Passport Network authentication as the default authentication mode.
None:
Specifies no authentication. Your application expects only anonymous users or the application provides its own authentication.
The authentication element configures the ASP.NET authentication scheme for an ASP.NET application. The authentication scheme determines how to identify users who want to view the ASP.NET application.
