 Configuring Custom Passwords
 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 
-In order to write additional passwords to ``passwords.yml``, set the kayobe
-variable ``kolla_ansible_custom_passwords`` in
-``$KAYOBE_CONFIG_PATH/kolla.yml``.
+The following variables are used to configure custom passwords:
+
+* ``kolla_ansible_default_custom_passwords``: Dictionary containing default
+  custom passwords, required by Kolla Ansible. Contains SSH keys authorized by
+  kolla user on Kolla hosts, SSH keys authorized in hosts deployed by Bifrost,
+  Docker Registry password and compute libVirt custom passwords.
+* ``kolla_ansible_extra_custom_passwords``: Dictionary containing extra custom
+  passwords to add or override in the Kolla passwords file. Default is an empty
+  dictionary.
+* ``kolla_ansible_custom_passwords``: Dictionary containing custom passwords to
+  add or override in the Kolla passwords file. Default is the combination of
+  the ``kolla_ansible_default_custom_passwords`` and
+  ``kolla_ansible_extra_custom_passwords``.
+
+In this example we add our own ``my_custom_password`` and override
+``keystone_admin_password``:
 
 .. code-block:: yaml
    :caption: ``$KAYOBE_CONFIG_PATH/kolla.yml``
 
    ---
-   # Dictionary containing custom passwords to add or override in the Kolla
-   # passwords file.
-   kolla_ansible_custom_passwords: >
-     {{ kolla_ansible_default_custom_passwords |
-        combine({'my_custom_password': 'correcthorsebatterystaple'}) }}
+   # Dictionary containing extra custom passwords to add or override in the
+   # Kolla passwords file.
+   kolla_ansible_extra_custom_passwords:
+     my_custom_password: 'correcthorsebatterystaple'
+     keystone_admin_password: 'superduperstrongpassword'

+fixes:
+  - |
+    Fixes an issue when user forgot to combine
+    ``kolla_ansible_custom_passwords``,
+    ``kolla_ansible_default_custom_passwords`` and own dictionary with custom
+    passwords in configuration files. Now
+    ``kolla_ansible_extra_custom_passwords`` should provide only user custom
+    passwords to add or override in the passwords.yml.
+upgrade:
+  - |
+    Now no need to combine ``kolla_ansible_default_custom_passwords`` and
+    ``kolla_ansible_custom_passwords`` in your custom configuration. Just use
+    ``kolla_ansible_extra_custom_passwords`` to add or override passwords.
