System.Web.Security Namespace

Represents a user identity authenticated using forms authentication. This class cannot be inherited.

The FormsIdentity class is used by the FormsAuthenticationModule when a user is authenticated with forms authentication. An instance of the FormsIdentity class is created using the FormsAuthenticationTicket that is decrypted from the forms-authentication cookie or from the URL. The new instance of the FormsIdentity class is used to construct a new GenericPrincipal object that is set as the value of the User property for the current HttpContext.
