How can I use Django OAuth Toolkit with Python Social Auth?

I’m building an API using Django Rest Framework. Later this API is supposed to be consumed by iOS and Android devices. I want to allow my users to sign-up with oauth2-providers like Facebook and Google. In this case, they shouldn’t have to create an account with my platform at all. But users should also be able to sign-up when not having a Facebook/Google account, for which I’m using django-oauth-toolkit, so I have my own oauth2-provider.
