 To blind additional configuration options in the Configuration module a hook has been added:
 
-:php:`$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS'][\TYPO3\CMS\Lowlevel\ControllerConfigurationController::class]['modifyBlindedConfigurationOptions']`
+:php:`$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS'][\TYPO3\CMS\Lowlevel\Controller\ConfigurationController::class]['modifyBlindedConfigurationOptions']`
 
+This can be implemented e.g. by adding a class :php:`\MyVendor\MyExtension\Hook\BlindedConfigurationOptionsHook`:
+
+.. code-block:: php
+
+    class BlindedConfigurationOptionsHook
+    {
+        /**
+         * Blind something in ConfigurationOptions
+         *
+         * @param array $blindedConfigurationOptions
+         * @return array
+         */
+        public function modifyBlindedConfigurationOptions(array $blindedConfigurationOptions): array
+        {
+            if (!empty($GLOBALS['TYPO3_CONF_VARS']['EXTENSIONS']['example']['password'])) {
+                $blindedConfigurationOptions['TYPO3_CONF_VARS']['EXTENSIONS']['example']['password'] = '******';
+            }
+
+            return $blindedConfigurationOptions;
+        }
+    }
+
+and adding the following line to ext_localconf.php:
+
+.. code-block:: php
+
+    $GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS'][\TYPO3\CMS\Lowlevel\Controller\ConfigurationController::class]['modifyBlindedConfigurationOptions'][] = \MyVendor\MyExtension\Hook\BlindedConfigurationOptionsHook::class;
