However ASP.NET also includes a robust authentication mechanism that can provide even greater security for a Web site. In the next section I will examine the implementation of authentication in ASP.NET. Implementing Authentication in ASP.NET In addition to IIS ASP.NET implements its own authentication mechanism. This mechanism is based on the XML-based configuration of the application in the Web.config file. In this section I will describe the types of authentication mechanisms supported by ASP.NET. Then I ll examine the steps to implement two authentication mechanisms Forms authentication and Windows authentication. Types of Authentication in ASP.NET ASP.NET supports three types of authentication mechanisms Forms authentication Passport authentication and Windows authentication. Forms authentication.
