NAME

       pam_passwdqc — Password quality-control PAM module

SYNOPSIS

       [service-name] module-type control-flag pam_passwdqc [options]

DESCRIPTION

       The  pam_passwdqc  module is a simple password strength checking module for PAM.  In addition to checking
       regular passwords, it offers support for passphrases and can provide randomly generated ones.

       The pam_passwdqc module provides functionality for only one PAM management group: password changing.   In
       terms of the module-type parameter, this is the “password” feature.

       The  pam_chauthtok()  service  function  may  ask  the  user for a new password, and verify that it meets
       certain minimum standards.  If the chosen  password  is  unsatisfactory,  the  service  function  returns
       PAM_AUTHTOK_ERR.

       The set of options that may be passed to the module is exactly the same as the set of options that may be
       specified in the /etc/passwdqc.conf file.  These options are described in passwdqc.conf(5).

AUTHORS

       The  pam_passwdqc  module was written for Openwall GNU/*/Linux by Solar Designer <solar at openwall.com>.
       This manual page was written for the FreeBSD Project by ThinkSec AS and NAI Labs, the  Security  Research
       Division  of  Network Associates, Inc. under DARPA/SPAWAR contract N66001-01-C-8035 (“CBOSS”), as part of
       the  DARPA  CHATS  research  program.   It  has  since  been  revised,  most  importantly  to  refer   to
       passwdqc.conf(5) instead of describing the options right on this page.
