How do I set up authentication in Django?

To set up authentication in Django, you need to configure the authentication backend in your settings.py file.

What is an authentication backend?

An authentication backend is a class that defines how Django authenticates users. You can create custom backends or use the default ones.

Can you show me an example of a custom authentication backend?

Sure! A custom backend might look like this:

from django.contrib.auth.backends import BaseBackend
from django.contrib.auth.models import User

class MyCustomBackend(BaseBackend):
    def authenticate(self, request, username=None, password=None):
        try:
            user = User.objects.get(username=username)
            if user.check_password(password):
                return user
        except User.DoesNotExist:
            return None
