Overriding Fluid templates 

All frontend output is rendered via Fluid templates located in EXT:nr_passkeys_fe/Resources/Private/. Override any template by registering a higher-priority path:

plugin.tx_nrpasskeysfe {
    view {
        templateRootPaths.10 = EXT:my_ext/Resources/Private/Templates/NrPasskeysFe/
        partialRootPaths.10 = EXT:my_ext/Resources/Private/Partials/NrPasskeysFe/
        layoutRootPaths.10 = EXT:my_ext/Resources/Private/Layouts/NrPasskeysFe/
    }
}

Available templates:

• Login/Index.html -- Passkey login form
• Login/Recovery.html -- Recovery code login form
• Enrollment/Index.html -- Passkey enrollment form
• Enrollment/Success.html -- Post-enrollment success page
• Management/Index.html -- Self-service management panel
• Management/RecoveryCodes.html -- Recovery code generation
• AdminModule/Index.html -- Backend admin module shell

Replacing services 

All services are registered in Configuration/Services.yaml with standard Symfony DI. To replace a service, add an alias in your extension's Services.yaml:

# Override the enforcement service
Netresearch\NrPasskeysFe\Service\FrontendEnforcementService:
  class: MyVendor\MyExt\Service\CustomEnforcementService

Custom enforcement via event 

The recommended approach for custom enforcement logic is to listen to EnforcementLevelResolvedEvent and call setEffectiveLevel():

use Netresearch\NrPasskeysFe\Event\EnforcementLevelResolvedEvent;

final class CustomEnforcementListener
{
    public function __invoke(EnforcementLevelResolvedEvent $event): void
    {
        // Exempt staff members from enforcement
        if ($this->isStaffMember($event->feUserUid)) {
            $event->setEffectiveLevel('off');
        }
    }
}

Adding custom eID endpoints 

The extension's eID dispatcher (EidDispatcher) is registered at eID=nr_passkeys_fe. It routes requests to controllers based on the action POST parameter.

To add custom eID actions without modifying the extension, listen to BeforePasskeyAuthenticationEvent for pre-auth hooks, or register your own eID handler in ext_localconf.php:

$GLOBALS['TYPO3_CONF_VARS']['FE']['eID_include']['my_passkey_ext']
    = \MyVendor\MyExt\Eid\MyEidHandler::class . '::handle';

JavaScript module overrides 

The extension's JavaScript modules are loaded as TYPO3 ES modules (@netresearch/nr-passkeys-fe/*). To customize behavior, extend the module via @typo3/core/event/regular-event.js hooks or override the import map in Configuration/JavaScriptModules.php.
