Did you have to create all the usual routes and views for the typical auth flow like signup, login, logout, change-password etc yourself?

I did a quick test like this:

    apt install -y python3-django
    django-admin startproject mysite
    cd mysite
    python3 manage.py migrate
    python3 manage.py runserver 0.0.0.0:80

And it serves a Django site but there seem to be no routes for users to sign up, log in etc.

The urls.py file contains only this one route it seems:

    urlpatterns = [
        url(r'^admin/', admin.site.urls),
    ]
