What authentication method is used in ASP.NET MVC sites?

Question

ASP.NET

I only know two ways. With Identity and forms authentication. What method do you use in your projects?

Answer 1

Identity 2.0
Omnivorous, out of the box.
No need to invent a bicycle with vulnerabilities, this is the best I've seen.
ASP.NET Identity 2.0.
ASP.NET Identity 2.0 includes several new features like Two-Factor Authentication, Account Lockout, Account Confirmation, Password Reset, Security Stamp (Sign-Out Everywhere) and more. Before, these features had to be coded, so now developers can focus more on main business while using tested and standardized method to manage users.
