@ -82,3 +82,13 @@ Password auth provider classes may optionally provide the following methods.
The method should return a Twisted ``Deferred`` object, which resolves to
``True`` if authentication is successful, and ``False`` if not.
``someprovider.on_logged_out``\(*user_id*, *device_id*, *access_token*)
This method, if implemented, is called when a user logs out. It is passed
the qualified user ID, the ID of the deactivated device (if any: access
tokens are occasionally created without an associated device ID), and the
(now deactivated) access token.
It may return a Twisted ``Deferred`` object; the logout request will wait
for the deferred to complete but the result is ignored.
