systemd-tty-ask-password-agent [OPTIONS...] [VARIABLE=VALUE...]
systemd-tty-ask-password-agent is a password agent that handles password requests of the system, for example for hard disk encryption passwords or SSL certificate passwords that need to be queried at boot-time or during runtime.
The following options are understood:

Process all currently pending system password requests by querying the user on the calling TTY.
Continuously process password requests.
Forward password requests to wall(1) instead of querying the user on the calling TTY.

the calling TTY. If
DEVICE is not specified,
/dev/console will be used.
On success, 0 is returned, a non-zero failure code otherwise.
