What is the use of Login control in ASP.NET

Login Security Control: This is a composite control that ties into the ASP.NET membership features. It contains TextBox controls for entering a username and password, as well as a Submit button. This control also includes a number of customizable features, including formatting and all the various pieces of text that can appear, such as instructional text, login failed text, and title text for the control. You can also choose to have the control display hyperlinks to registration and password recovery pages.

The Login control even includes built-in required field validation for both username and password. (Validation can be disabled.) You can write code to support a Login controlin the Authenticate event handler. Even the simplest use of the Login control with absolutely zero code provides a complete working authentication interface.
