What is the difference between login controls and Forms authentication?

• Forms authentication can be easily implemented using login controls without writing any code.
• Login control performs functions like prompting for user credentials, validating them and issuing authentication just as the FormsAuthentication class.
• However, all that’s needs to be dne is to drag and drop the use control from the tool box to have these checks performed implicitly. 

The FormsAuthentication class is used in the background for the authentication ticket and ASP.NET membership is used to validate the user credentials
