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 configuration file
     (suggested location /etc/passwdqc.conf, to be specified in the
     config=/etc/passwdqc.conf option).  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.
