-# /etc/pam.d/common-password - password-related modules common to all services
-#
-# This file is included from other service-specific PAM config files,
-# and should contain a list of modules that define the services to be
-# used to change user passwords.  The default is pam_unix.
-
-# Explanation of pam_unix options:
-# The "yescrypt" option enables
-#hashed passwords using the yescrypt algorithm, introduced in Debian
-#11.  Without this option, the default is Unix crypt.  Prior releases
-#used the option "sha512"; if a shadow password hash will be shared
-#between Debian 11 and older releases replace "yescrypt" with "sha512"
-#for compatibility .  The "obscure" option replaces the old
-#`OBSCURE_CHECKS_ENAB' option in login.defs.  See the pam_unix manpage
-#for other options.
-
-# As of pam 1.0.1-6, this file is managed by pam-auth-update by default.
-# To take advantage of this, it is recommended that you configure any
-# local modules either before or after the default block, and use
-# pam-auth-update to manage selection of other modules.  See
-# pam-auth-update(8) for details.
