LoginAttemptFailedEvent¶

New in version 12.3: The event replaces the deprecated hook $GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['t3lib/class.t3lib_userauth.php']['postLoginFailureProcessing'] .

The purpose of the PSR-14 event \TYPO3\CMS\Core\Authentication\Event\LoginAttemptFailedEvent is to allow to notify remote systems about failed logins.

Example¶

EXT:my_extension/Authentication/EventListener/MyEventListener.php¶

<?php

declare(strict_types=1);

namespace MyVendor\MyExtension\Authentication\EventListener;

use TYPO3\CMS\Core\Attribute\AsEventListener;
use TYPO3\CMS\Core\Authentication\Event\LoginAttemptFailedEvent;

#[AsEventListener(
    identifier: 'my-extension/login-attempt-failed'
)]
final class MyEventListener
{
    public function __invoke(LoginAttemptFailedEvent $event): void
    {
        $normalizedParams = $event->getRequest()->getAttribute('normalizedParams');
        if ($normalizedParams->getRemoteAddress() !== '198.51.100.42') {
            // send an email because an external user attempt failed
        }
    }
}

New in version 13.0: The PHP attribute \TYPO3\CMS\Core\Attribute\AsEventListener has been introduced to tag a PHP class as an event listener. Alternatively, or if you need to be compatible with older TYPO3 versions, you can also register an event listener via the Configuration/Services.yaml file. Switch to an older version of this page for an example or have a look at the section Implementing an event listener in your extension.
