Answer 1

allauth
python-social-auth also writes to the user base

Answer 2

Interestingly, this question remains unanswered.
Judging by the modules, python-social-auth is used, which replaced django-social-auth.
This code uses a slightly different format for composing the link. {% url 'socialauth_begin' 'vk-oauth' %}
All the examples in the documentation use a slightly different format for composing the link, namely {% url 'social:begin' 'vk-oauth2' %}
The error is that it could not find a view that matches "socialauth_begin".
The config included URLs from python-social-auth. python-social-auth suggests using namespaces. What is it and why is it well described in the documentation .
The general view for creating "login" links in python-social-auth looks like this: {% url 'social:begin' 'auth_backend' %}. Will create a link to example.com/where_social.apps.django.urls/login/auth_backend/ are installed.
