Confirm Accout before login MVC 5

Hello everyone,

i am trying to make some thing in asp.net mvc 5. I want the user to register after click on register he/she should be directed to the enter your code dialogue view. i have included PhoneNumber option in registration form, ( i know how to send code via Twillo) Now i want if the user enter the correct code he/she should be logged in and if not, the account registration should stay until its phone number is confirmed. also i want this the login view.

How can i do that?

Visual Studio 2015.

Thanks in advance.
