Redirecting to a custom Windows Authentication login page if the user is anonymous in ASP.NET MVC

Question

I have an ASP.NET MVC intranet site using Windows Authentication. It is configured from the default project for ASP.NET MVC using Windows Authentication. I am trying to find information on overriding the login popup by default if the user is not authenticated / anonymous.

The default login request is:

Everything I find on the Internet is almost 10 years old using classic ASP or Web Forms. Nothing I can find is using ASP.NET MVC.

I would like the user to be redirected to the login view if he is anonymous / not authenticated. In addition, the ability to exit the system if they are automatically authenticated and registered as another user.

The main problem is that I cannot find where the actual authentication is performed in my project. I checked App_Start, Global.asaxetc. I can not find how to redefine it.

I know that for my part there is a lack of code, but I would appreciate it if someone had a good starting point or experience with this requirement.
