================================================================================================================
Deprecation: #85960 - AbstractUserAuthentication::compareUident and AbstractAuthenticationService->compareUident
================================================================================================================

See :issue:`85960`

Description
===========

Two methods related to old plain text or simple md5 related password checking have
been marked as deprecated after those have been unused or overridden for a while already:

* :php:`TYPO3\CMS\Core\Authentication\AbstractUserAuthentication->compareUident()`
* :php:`TYPO3\CMS\Core\Authentication\AbstractAuthenticationService->compareUident()`


Impact
======

Calling the above methods will trigger a PHP :php:`E_USER_DEPRECATED` error.


Affected Installations
======================

Instances using special authentication extensions  might be
affected. The extension scanner should find usages.


Migration
=========

Do not use plain text or simple md5 based password comparison in authentication services.
