Answer

You are using the same path for django.contrib.auth.urls and webportal.urls.

That means webportal/login/ is matched by django.contrib.auth.urls first, which uses the template registration/login.html.

You can switch the order of the includes so that login is matched by the pattern in webportal.urls first.

path("webportal/", include("webportal.urls", namespace="webportal")),
path("webportal/", include("django.contrib.auth.urls")),

Alternatively, since all you are changing is the template name, you could move the login template to webportal/templates/registration/login.html, remove your URL pattern, and let django.contrib.auth.urls handle logins.
