Searching for password in man unzip:

Code:
       -P password
              use  password  to  decrypt  encrypted  zipfile entries (if any).
              THIS IS INSECURE!  Many  multi-user  operating  systems  provide
              ways  for  any user to see the current command line of any other
              user; even on stand-alone systems there is always the threat  of
              over-the-shoulder  peeking.   Storing  the plaintext password as
              part of a command line in an automated  script  is  even  worse.
              Whenever  possible,  use  the non-echoing, interactive prompt to
              enter passwords.  (And where security is  truly  important,  use
              strong  encryption  such  as  Pretty Good Privacy instead of the
              relatively weak encryption provided by standard  zipfile  utili-
              ties.)

NAME

       systemd-ask-password-console.service, systemd-ask-password-console.path, systemd-ask-password-wall.service, systemd-ask-password-wall.path
       - Query the user for system passwords on the console and via wall

SYNOPSIS

       systemd-ask-password-console.service

       systemd-ask-password-console.path

       systemd-ask-password-wall.service

       systemd-ask-password-wall.path

DESCRIPTION

       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.

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