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.
