Django - Login with Email

I want django to authenticate users via email, not via usernames. One way can be providing email value as username value, but I dont want that. Reason being, I've a url /profile/<username>/, hence I cannot have a url /profile/abcd@gmail.com/. Another reason being that all emails are unique, but it happen sometimes that the username is already being taken. Hence I'm auto-creating the username as fullName_ID. How can I just change let Django authenticate with email? This is how I create a user. username = `abcd28` user_email = `abcd@gmail.com` user = User.objects.create_user(username, user_email, user_pass) This is how I login. email = request.POST['email'] password = request.POST['password'] username = User.objects.get(email=email.lower()).username user = authenticate(username=username, password=password) login(request, user) Is there any other of of login apart from getting the username first?
You should write a custom authentication backend. Something like this will work: from django.contrib.auth import get_user_model from django.contrib.auth.backends import ModelBackend class EmailBackend(ModelBackend): def authenticate(self, request, username=None, password=None, **kwargs): UserModel = get_user_model() try: user = UserModel.objects.get(email=username) except UserModel.DoesNotExist: return None else: if user.check_password(password): return user return None Then, set that backend as your auth backend in your settings: AUTHENTICATION_BACKENDS = ['path.to.auth.module.EmailBackend'] Updated. Inherit from ModelBackend as it implements methods like get_user() already. See docs here: https://docs.djangoproject.com/en/3.0/topics/auth/customizing/#writing-an-authentication-backend
