Sqlalchemy in Django with User Authentication Problem

Hi Everyone, I am using sqlalchemy instead of Django's ORM for my new website, and I am running into the incompatible user authentication issue, I am wondering if there are any good python authentication library that allows both facebook, google, twitter,etc login and its own email registration?

Hello. I want to register users. So I made a RegisterForm(ModelForm): Class Meta: model=User (from django.auten.contrib.User) no i display that form in a view and submit it. When i do form.is_valid(), i get this validation error: Your username and password didn't match. Please try again.
