Title:
  Password visible in systemd password prompt if user types too slow

Status in systemd package in Ubuntu:
  Invalid

Bug description:
  When systemd prompts for a password (for example, using systemctl
  without sudo and requiring authentication), it times out if the user
  does not type the password fast enough (after about 30 seconds or so).

  This results in the password becoming visible on the next prompt from
  bash (or whatever shell was being used) as the password is left on
  standard input.

  
  Perhaps this package should consume the input when timing out. Not sure if this is possible, but a security issue.
