A very common task in web applications revolves around determining who the current user is and whether or not they are authorized to access a particular resource.  To support these tasks, a suite of security controls is included in ASP.NET 2.0.  These controls include:

• Login
• Prompts user for login name and password
• Supports usual options such as Forgot Password link and Remember Password? checkbox
• Integrates with Membership provider
• LoginName
• A simple control that displays the current logged in user's name (or nothing if the user is not authenticated).
• LoginStatus
• Another simple but very common control, this one displays a link to the Login page if the user is not authenticated, otherwise it displays a link to the Logout page.
• LoginView
• Allows custom content to be displayed based on whether the user is logged in.
• Content can be customized for individual user roles.
• PasswordRecovery
• Displays a Forgot Your Password? dialog and allows you to easily choose one of several common mechanisms for sending or resetting a user's password
