+CubicWeb AuthTkt authentication policy
+--------------------------------------
 
-"""Authentication policies for cubicweb.pyramid."""
+When using the `cubicweb.pyramid.auth` module, which is the default in most
+cases, you may have to configure the behaviour of these authentication
+policies using standard's Pyramid configuration. You may want to configure in
+your pyramid configuration file:
+
+:Session Authentication:
+
+    This is a `AuthTktAuthenticationPolicy`_ so you may overwrite default
+    configuration values by adding configuration entries using the prefix
+    ``cubicweb.auth.authtkt.session``. Default values are:
+
+    ::
+
+        cubicweb.auth.authtkt.session.hashalg = sha512
+        cubicweb.auth.authtkt.session.cookie_name = auth_tkt
+        cubicweb.auth.authtkt.session.timeout = 1200
+        cubicweb.auth.authtkt.session.reissue_time = 120
+        cubicweb.auth.authtkt.session.http_only = True
+        cubicweb.auth.authtkt.session.secure = True
+
+
+:Persistent Authentication:
+
+    This is also a `AuthTktAuthenticationPolicy`_. It is used when persistent
+    sessions are activated (typically when using the cubicweb-rememberme_
+    cube). You may overwrite default configuration values by adding
+    configuration entries using the prefix
+    ``cubicweb.auth.authtkt.persistent``. Default values are:
+
+    ::
+
+        cubicweb.auth.authtkt.persistent.hashalg = sha512
+        cubicweb.auth.authtkt.persistent.cookie_name = pauth_tkt
+        cubicweb.auth.authtkt.persistent.max_age = 3600*24*30
+        cubicweb.auth.authtkt.persistent.reissue_time = 3600*24
+        cubicweb.auth.authtkt.persistent.http_only = True
+        cubicweb.auth.authtkt.persistent.secure = True
+
+
+.. Warning:: Legacy timeout values from the instance's
+             ``all-in-one.conf`` are **not** used at all (``
+             http-session-time`` and ``cleanup-session-time``)

+
+Secrets
+~~~~~~~
+There are a number of secrets to configure in ``pyramid.ini``. They
+should be different one from each other, as explained in `Pyramid's
+documentation`_.
+
+For the record, regarding authentication:
+
+:cubicweb.auth.authtkt.session.secret: This secret is used to encrypt
+   the authentication cookie.
+
+:cubicweb.auth.authtkt.persistent.secret: This secret is used to

+Web session when using pyramid
+------------------------------
 
-"""Pyramid session factories for CubicWeb."""
+CubicWeb ``CWSession`` entity type so that sessions can be
+stored in the database, which allows to run a Cubicweb instance
+without having to set up a session storage (like redis or memcache)
+solution.
+
+However, for production systems, it is greatly advised to use such a
+storage solution for the sessions.
+
+The handling of the sessions is made by pyramid (see the
+`pyramid's documentation on sessions`_ for more details).
+
+For example, to set up a redis based session storage, you need the
+`pyramid-redis-session`_ package, then you must configure pyramid to
+use this backend, by configuring the pyramid configuration file:
+
+
+.. code-block:: ini
+
+   [main]
+   cubicweb.defaults = no # we do not want to load the default cw session handling
+
+   cubicweb.auth.authtkt.session.secret = <secret1>
+   cubicweb.auth.authtkt.persistent.secret = <secret2>
+   cubicweb.auth.authtkt.session.secure = yes
+   cubicweb.auth.authtkt.persistent.secure = yes
+
+   redis.sessions.secret = <secret3>
+   redis.sessions.prefix = <my-app>:
+
+   redis.sessions.url = redis://localhost:6379/0
+
+   pyramid.includes =
+           pyramid_redis_sessions
+           cubicweb.pyramid.auth
+           cubicweb.pyramid.login
+
+
+.. Warning:: If you want to be able to log in a CubicWeb application
+             served by pyramid on a unsecured stream (typically when
+             you start an instance in dev mode using a simple
+             ``cubicweb-ctl pyramid -D -linfo myinstance``), you
+             **must** set ``cubicweb.auth.authtkt.session.secure`` to
+             ``no``.
+
+Secrets
+~~~~~~~
+
+There are a number of secrets to configure in ``pyramid.ini``. They
+should be different one from each other, as explained in `Pyramid's
+documentation`_.
+
+For the record, regarding session handling:
+
+:cubicweb.session.secret: This secret is used to encrypt the session's
+   data ID (data themselved are stored in the backend, database or
+   redis) when using the integrated (``CWSession`` based) session data
+   storage.
+
+:redis.session.secret: This secret is used to encrypt the session's
+   data ID (data themselved are stored in the backend, database or
+   redis) when using redis as backend.
