=============================
Linux Accounts Password Rules
=============================
.. rubric:: Check Current Password Expiry Settings
Before making any changes, you may want to check the current password expiry
settings for the user. You can do this by running the :command:`chage -l
<username>` command, replacing ``<username>`` with the name of the user whose
password expiry settings you want to view.
.. code-block:: none
sudo chage -l <username>
.. rubric:: Change Password Expiry Settings
To change the password expiry period of Linux accounts, run the
:command:`chage` command, as below:
.. code-block:: none
[sysadmin@controller-0 ~(keystone_admin)]$ sudo chage -M <days_to_expiry> <username>
For example, to set the maximum number of days before the password must be
changed to 60 days for a user named ``sysadmin``, you can use the following
command:
.. code-block:: none
[sysadmin@controller-0 ~(keystone_admin)]$ sudo chage -M 60 sysadmin
Verify Changes
--------------
After making the changes, verify that the new password expiry settings have
been applied by running the :command:`chage -l <username>` command again.
.. code-block:: none
chage -l <username>
For the example above of user ``sysadmin`` and expiry period of 60 days, the
output of ``chage -l <username>`` should be as follows:
.. code-block:: none
[sysadmin@controller-0 ~(keystone_admin)]$ chage -l sysadmin
