There are two option with you; 1. Either use a ASP.net membership provider class it has a default functionality implemented which locks he users after a certain unsuccessfull login attempts. 2. Add a cloumnIsLockedOut of datatype boolean to your user table and while a user attemts to login just count the number of attempts if its a unsucessfull login. When the count gets 3 set IslockedOut column in the table to true for that particular user.So even if the user tries to login with correct credentials he wont able to login. So when a user login you will have to check UsernamePassword and IsLockedOut in your logic. If the IsLockedOut flag is false then allow the user to login if his username and password is correct else deny him to login even if other credentials are correct.
