[Django]-Django Authenticate always returns None with correct credentials also

The problem is django’s default authentication mechanism don’t allow you authenticate using email, you can only authenticate user using username .
either way, you can get the user’s username from the User model using his email and then you can authenticate user.

    def login(request):
        if request.method == 'POST':
            email = request.POST['email']
            password = request.POST['password']
            username = ''
            try:
                username = User.objects.get(email=email).username
            except User.DoesNotExist:
                return HttpResponse("Invalid")
            user = authenticate(request, username=username, password=password)
            if user is not None:
                login(request, user)
                print("Logged in")
            else:
                print("not logged in")
            return redirect('/')
        else:
            return HttpResponse("Invalid")

Also dont store password directly, always user standard set_password() function of django

            if User.objects.filter(email=email).exists():
                print("Email taken")
            elif User.objects.filter(username=user_name).exists():
                print("Username taken")
            else:        
                user = User.objects.create_user(username = user_name, first_name=first_name,last_name=last_name, email=email)
                user.set_password(pass1)
                user.save()
                print("User created")

The problem is your signup method. You should not give password to the init function. You should use User’s set_password method.

In your sign_up view remove password=pass1 at the line where you are creating User object. And after that before saving the user, add user.set_password(pass1).

Hope this helps!
