BeforeRequestTokenProcessedEvent 

Example 

The event can be used to generate the request token individually. This can be the case when you are not using a login callback and have not the possibility to submit a request token:

Registration of the event listener in the extension's Services.yaml:

services:
  # Place here the default dependency injection configuration

  MyVendor\MyExtension\Authentication\EventListener\MyEventListener:
    tags:
      - name: event.listener
        identifier: 'my-extension/process-request-token-listener'

Read how to configure dependency injection in extensions.

An implementation of the event listener:

<?php

declare(strict_types=1);

namespace MyVendor\MyExtension\Authentication\EventListener;

use TYPO3\CMS\Core\Authentication\Event\BeforeRequestTokenProcessedEvent;
use TYPO3\CMS\Core\Security\RequestToken;

final class MyEventListener
{
    public function __invoke(BeforeRequestTokenProcessedEvent $event): void
    {
        $user = $event->getUser();
        $requestToken = $event->getRequestToken();
        // fine, there is a valid request token
        if ($requestToken instanceof RequestToken) {
            return;
        }

        // Validate individual requirements/checks
        // ...
        $event->setRequestToken(
            RequestToken::create('core/user-auth/' . strtolower($user->loginType)),
        );
    }
}
