+#### Manage faillock
+
+Management of faillock and faillock.conf is enabled via `pam::manage_faillock`.
+
+The following example would enable faillock, configure it, and add it to the PAM stack.
+
+```yaml
+pam::manage_faillock: true
+pam::faillock::deny: 3
+pam::pam_auth_lines:
+  - 'auth        required      pam_env.so'

+
+#### Manage pwquality
+
+Management of pwquality and pwquality.conf is enabled via `pam::manage_pwquality`.
+
+The following example would enable pwquality, configure it, and add it to the PAM stack.
+
+```yaml
+pam::manage_pwquality: true
+pam::pwquality::retry: 3
+pam::pwquality::maxclassrepeat: 4
