.. include:: /Includes.rst.txt .. _deprecation-100278-1679605129: ====================================================== Deprecation: #100278 - PostLoginFailureProcessing hook ====================================================== See :issue:`100278` Description =========== The hook :php:`$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['t3lib/class.t3lib_userauth.php']['postLoginFailureProcessing']` which can be used to handle custom notifications that a login in a frontend or backend context failed, has been marked as deprecated. Impact ====== If the hook is registered in a TYPO3 installation, a PHP :php:`E_USER_DEPRECATED` error is triggered. The extension scanner also detects any usage of the deprecated interface as a strong match, and the definition of the hook as a weak match. Affected installations ====================== TYPO3 installations with custom extensions using this hook. Migration ========= Migrate to the newly introduced PSR-14 event :ref:`\\TYPO3\\CMS\\Core\\Authentication\\Event\\LoginAttemptFailedEvent `. .. index:: Backend, Frontend, PHP-API, FullyScanned, ext:core
