How to override User model after migrations?

Question

Django

Migrations already applied (together with the django.contrib.auth application)
The project is working, but the auth.User model is not used anywhere yet, except, apparently, in the admin panel.
You need to override it by making registration only by email.
The problem is that janga is not designed for such a maneuver. I found some manuals, but there is not enough experience to figure it out.
Those. the plan, if I had started before migrating, would have been: User(AbstractBaseUser), USERNAME_FIELD='email', REQUIRED_FIELDS=[], didn't seem to have forgotten anything.

No one bothers you to inherit AbstractBaseUser with your own class like: CustomUser.
https://docs.djangoproject.com/en/2.0/topics/auth/...
And you can do authorization via email this way.

def auth(request):
    email = request.POST['email']
    password = request.POST['password']
    get_user = get_object_or_404(User, email=email)
    user = authenticate(username=get_user.username, password=password)
    if user is not None and user.is_active:
        login(request, user)
        return HttpResponseRedirect(reverse('shop:index'))
