Password quality-control PAM module
SYNOPSIS¶
[service-name

pam_passwdqc
[options
]
DESCRIPTION¶
Thepam_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).

Thepam_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.March 13, 2010 | Openwall Project |
