Policy Requires Immediate Change of Temporary Passwords

Description

Temporary passwords for Ubuntu 20.04 operating system logons must require an immediate change to a permanent password. Verify that a policy exists that ensures when a user is created, it is creating using a method that forces a user to change their password upon their next login.

Rationale

Without providing this capability, an account may be created without a password. Nonrepudiation cannot be guaranteed once an account is created if a user is not forced to change the temporary password upon initial logon. Temporary passwords are typically used to allow access when new accounts are created or passwords are changed. It is common practice for administrators to create temporary passwords for user accounts that allow the users to log on, yet force them to change the password once they have successfully authenticated.
