[Answered ]-Django authenticate returning Nonetype with valid credentials

✅

When you use MyUserModel.objects.create(...), the password is stored in the database in plain text. The call to authenticate does not work, because Django expects the password to be hashed in the database.

Therefore, when you create a user, you need to ensure that the password is hashed, rather than being stored in plain text in the database. You can do this by calling user.set_password('new_password').

The full example in the docs shows a create_user manager method that calls set_password when creating the user. You would then use MyUserModel.objects.create_user(...) instead of MyUserModel.objects.create(...).

class MyUserManager(BaseUserManager):
    def create_user(self, email, date_of_birth, password=None):
        """
        Creates and saves a User with the given email, date of
        birth and password.
        """
        if not email:
            raise ValueError('Users must have an email address')

        user = self.model(
            email=self.normalize_email(email),
            date_of_birth=date_of_birth,
        )

        user.set_password(password)
        user.save(using=self._db)
        return user
