On django version 2.1 or above, you should pass the request into function authenticate for the customized authentication. For example:

class PasswordlessAuthenticationBackend(object):

    def authenticate(self, request, uid):
        try:
            token = Token.objects.get(uid=uid)
            print('got user', file=sys.stderr)
            return ListUser.objects.get(email=token.email)
        except ListUser.DoesNotExist:
            print('new user', file=sys.stderr)
            return ListUser.objects.create(email=token.email)
        except Token.DoesNotExist:
            return None

Finally, don't forget the settings in settings.py: 1. accounts is your app name 2. ListUser is your model name

AUTH_USER_MODEL = 'accounts.ListUser'
AUTHENTICATION_BACKENDS = (
    'accounts.authentication.PasswordlessAuthenticationBackend',
)
