PAM_PASSWDQC(8)

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.
