+Authentication
+==============
+
+Overview
+--------
+
+A default authentication stack is provided by the :mod:`cubicweb.pyramid.auth`
+module, which is included by :mod:`cubicweb.pyramid.default`.
+
+The authentication stack is built around `pyramid_multiauth`_, and provides a
+few default policies that reproduce the default cubicweb behavior.
+
+.. note::
+
+    Note that this module only provides an authentication policy, not the views
+    that handle the login form. See :ref:`login_module`
+
+Customize
+---------
+
+The default policies can be individually deactivated, as well as the default
+authentication callback that returns the current user groups as :term:`principals`.
+
+The following settings can be set to `False`:
+
+-   :confval:`cubicweb.auth.update_login_time`. Activate the policy that update
+    the user `login_time` when `remember` is called.
+-   :confval:`cubicweb.auth.authtkt` and all its subvalues.
+-   :confval:`cubicweb.auth.groups_principals`
+
+Additionnal policies can be added by accessing the MultiAuthenticationPolicy
+instance in the registry:
+
+.. code-block:: python
+
+    mypolicy = SomePolicy()
+    authpolicy = config.registry['cubicweb.authpolicy']
+    authpolicy._policies.append(mypolicy)
