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 for more information about the system password logic.
Note that these services invoke systemd-tty-ask-password-agent(1) with either the --watch --console or --watch --wall command line parameters.
