+pam_pwhistory — PAM module to remember last passwords
+
+━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
+
+DESCRIPTION
+
+This module saves the last passwords for each user in order to force password
+change history and keep the user from alternating between the same password too
+frequently.
+
+This module does not work together with kerberos. In general, it does not make
+much sense to use this module in conjunction with NIS or LDAP, since the old
+passwords are stored on the local machine and are not available on another
+machine for password history checking.
+
+OPTIONS
+
+debug
+
+    Turns on debugging via syslog(3).
+
+use_authtok
+
+    When password changing enforce the module to use the new password provided
+    by a previously stacked password module (this is used in the example of the
+    stacking of the pam_cracklib module documented below).
+
+enforce_for_root
+
+    If this option is set, the check is enforced for root, too.
+
+remember=N
+
+    The last N passwords for each user are saved in /etc/security/opasswd. The
+    default is 10.
+
+retry=N
+
+    Prompt user at most N times before returning with error. The default is 1.
+
+authtok_type=STRING
+
+    See pam_get_authtok(3) for more details.
+
+EXAMPLES
+
+An example password section would be:
+
+#%PAM-1.0
+password     required       pam_pwhistory.so
+password     required       pam_unix.so        use_authtok
+
+
+In combination with pam_cracklib:
+
+#%PAM-1.0
+password     required       pam_cracklib.so    retry=3
+password     required       pam_pwhistory.so   use_authtok
+password     required       pam_unix.so        use_authtok
