+ <title>Description</title>
+
+ <para><command>systemd-ask-password</command> may be
+ used to query a system password or passphrase from the
+ user, using a question message specified on the
+ command line. When run from a TTY it will query a
+ password on the TTY and print it to STDOUT. When run
+ with no TTY or with <option>--no-tty</option> it will
+ query the password system-wide and allow active users
+ to respond via several agents. The latter is
+ only available to privileged processes.</para>
+
+ <para>The purpose of this tool is to query system-wide
+ passwords -- that is passwords not attached to a
+ specific user account. Examples include: unlocking
+ encrypted hard disks when they are plugged in or at
+ boot, entering an SSL certificate passphrase for web
+ and VPN servers.</para>
+
+ <para>Existing agents are: a boot-time password agent
+ asking the user for passwords using Plymouth; a
+ boot-time password agent querying the user directly on
+ the console; an agent requesting password input via a
+ <citerefentry><refentrytitle>wall</refentrytitle><manvolnum>1</manvolnum></citerefentry>
+ message; an agent suitable for running in a GNOME
+ session; a command line agent which can be started
+ temporarily to process queued password requests; a TTY
+ agent that is temporarily spawned during
+ <citerefentry><refentrytitle>systemctl</refentrytitle><manvolnum>1</manvolnum></citerefentry>
+ invocations.</para>
+
+ <para>Additional password agents may be implemented
+ according to the <ulink
+ url="http://www.freedesktop.org/wiki/Software/systemd/PasswordAgents">systemd
+ Password Agent Specification</ulink>.</para>
+
+ <para>If a password is queried on a tty the user may
+ press TAB to hide the asterisks normally shown for
+ each character typed. Pressing Backspace as first key
+ achieves the same effect.</para>
