pam_passwdqc: Password quality-control PAM module
pam_passwdqc - Password quality-control PAM module
SYNOPSIS[service-name ] module-type control-flag pam_passwdqc [options ]
DESCRIPTIONThe 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 module provides functionality for only one PAM management group: password changing. In terms of the module-type parameter, this is the ``password '' feature.
The Fn 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
AUTHORSThe module was written for Openwall GNU/*/Linux by An Solar Designer Aq solar at openwall.com . This manual page was written for the Fx 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.conf5 instead of describing the options right on this page.
