AfterUserLoggedInEvent

New in version 12.3: The event replaces the deprecated hook $GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['t3lib/class.t3lib_userauthgroup.php']['backendUserLogin'].

The purpose of the PSR-14 event \TYPO3\CMS\Core\Authentication\Event\AfterUserLoggedInEvent is to trigger any kind of action when a backend user has been successfully logged in.

The TYPO3 Core itself uses this event in the TYPO3 backend to send an email to a user, if the user has successfully logged in. See EXT:backend/Classes/Security/EmailLoginNotification.php.

Example

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

EXT:my_extension/Configuration/Services.yaml

MyVendor\MyExtension\Authentication\EventListener\MyEventListener:
  tags:
    - name: event.listener
      identifier: 'my-extension/after-user-logged-in'

An implementation of the event listener:

EXT:my_extension/Authentication/EventListener/MyEventListener.php

<?php

declare(strict_types=1);

namespace MyVendor\MyExtension\Authentication\EventListener;

use TYPO3\CMS\Core\Authentication\BackendUserAuthentication;
use TYPO3\CMS\Core\Authentication\Event\AfterUserLoggedInEvent;

final class MyEventListener
{
    public function __invoke(AfterUserLoggedInEvent $event): void
    {
        if (
            $event->getUser() instanceof BackendUserAuthentication
            && $event->getUser()->isAdmin()
        ) {
            // Do something like: Clear all caches after login
        }
    }
}
