15Available authentication backends
16=================================
17
18The following backends are available in :mod:`django.contrib.auth.backends`:
19
20.. class:: ModelBackend
21
22    This is the default authentication backend used by Django.  It
23    authenticates using usernames and passwords stored in the
24    :class:`~django.contrib.auth.models.User` model.
25
26
27.. class:: RemoteUserBackend
28
29    Use this backend to take advantage of external-to-Django-handled
30    authentication.  It authenticates using usernames passed in
31    :attr:`request.META['REMOTE_USER'] <django.http.HttpRequest.META>`.  See
32    the :doc:`Authenticating against REMOTE_USER </howto/auth-remote-user>`
33    documentation.
