Best practice to make custom user authentication form in ASP.NET

Question

I want to implement the user authentication and login page in ASP.NET, I want to make it highly secure, its a vast field and i didnt find any appropriate answer from the net search. Please, if anyone knows, refer me a best example for its implementation handling sessions, encryption and everything else that is need for a high security(which is my major concern) and prevention from Bots. I ve already implemented simple user authentication insertion deletion and login with simple SQL queries via stored procedures yet m sure its not enough.

Thanks MGD
