Auth in Django

A User model, already built

Every Flask or FastAPI project you'll ever write needs its own User table, its own password hashing, its own login endpoint. Django ships all of it: django.contrib.auth gives you a User model, createsuperuser, password hashing, and a login view — nothing to design.

request.user is available on every view. Log in, and it's a User instance; not logged in, and it's an AnonymousUser. Either way, request.user.is_authenticated just works.
