I like to use the authentication machinery in Django, without explicitly putting 'django.contrib.auth' in INSTALLED_APPS. This prevents a bunch of unused tables from being creating in the database.
This was possible in earlier version of Django. In 1.8, a spurious warning was generated, but that was fixed in #24564 (https://groups.google.com/forum/#!searchin/django-developers/$2324564/django-developers/7b4xzkjLFH8/wLJ83Bxa_h4J) In Django 1.9, it doesn't seem possible anymore (see traceback). Using the auth stuff without installing the app -- is that something we want to support or not?
