systemd-ask-password-console.service is a system service that queries the user for system passwords (such
as hard disk encryption keys and SSL certificate passphrases) on the console. It is intended to be used
during boot to ensure proper handling of passwords necessary for boot. systemd-ask-password-wall.service
is a system service that informs all logged in users for system passwords via wall(1). It is intended to
be used after boot to ensure that users are properly notified.
See the developer documentation[1] for more information about the system password logic.

--watch --wall command line parameters.
