Breaking: #96616 - Remove Frontend Login Mode for pages

See forge#96616


In order to reduce complexity for frontend requests, the rarely used frontend user login mode functionality has been removed.

It previously allowed to define branches, which should behave as if a user or usergroup was not logged in, even though a user was kept logged in as the cookie was not removed during such a request. This feature was only introduced back in 2004 by Kasper to overcome caching issues on and is considered an edge-case feature, which is better suited in an extension solved via a PSR-15 middleware nowadays.

As a consequence, next to the corresponding DB / TCA field pages.fe_login_mode the following public methods have been removed:

  • \TYPO3\CMS\Frontend\Authentication\FrontendUserAuthentication->hideActiveLogin()
  • \TYPO3\CMS\Frontend\Controller\TypoScriptFrontendController->checkIfLoginAllowedInBranch()

Additionally, the following TypoScript configuration has no effect anymore:

  • config.sendCacheHeaders_onlyWhenLoginDeniedInBranch


The functionality is no longer part of TYPO3 Core. Calling the related methods in custom extension code will lead to a fatal PHP error. The extension scanner will detect usages as weak match.

Affected Installations

TYPO3 installations currently using the functionality or calling the mentioned methods in custom extension code, which is very unlikely.

This can be checked by searching for database records in the DB "pages" table having "fe_login_mode > 0".


Remove any usage of the mentioned methods.

In case you currently rely on the functionality, use the upgrade wizard provided by the install tool to fetch and load the public fe_login_mode extension from TER. This extension provides the same functionality using a PSR-15 middleware.
