 to create and validate hashed passwords. You can use them independently
 from the ``User`` model.

     If you'd like to manually authenticate a user by comparing a plain-text
     password to the hashed password in the database, use the convenience
-    function :func:`check_password`. It takes two arguments: the plain-text
-    password to check, and the full value of a user's ``password`` field in the
-    database to check against, and returns ``True`` if they match, ``False``
-    otherwise.
+    function :func:`check_password`. It takes two mandatory arguments: the
+    plain-text password to check, and the full value of a user's ``password``
+    field in the database to check against. It returns ``True`` if they match,
+    ``False`` otherwise. Optionally, you can pass a callable ``setter`` that
+    takes the password and will be called when you need to regenerate it. You
+    can also pass ``preferred`` to change a hashing algorithm if you don't want
+    to use the default (first entry of ``PASSWORD_HASHERS`` setting). See
+    :ref:`auth-included-hashers` for the algorithm name of each hasher.
