+================================================================================
+Deprecation: #84274 - Protected methods and properties in LoginController
+================================================================================
+
+See :issue:`84274`
+
+Description
+===========
+
+This file is about third party usage (consumer that call the class as well as
+signals or hooks depending on it) of :php:`TYPO3\CMS\Backend\Controller\LoginController`.
+
+All methods not used as entry points by :php:`TYPO3\CMS\Backend\Http\RouteDispatcher` will be
+removed or set to protected in v10 and throw deprecation warnings if used from a third party:
+
+* [not scanned] :php:`main()`
+* :php:`makeInterfaceSelectorBox()`
+
+
+Impact
+======
+
+Calling above method on an instance of
+:php:`LoginController` will throw a deprecation warning in v9 and a PHP fatal in v10.
+
+
+Affected Installations
+======================
+
+The extension scanner will find all usages, but may also find some false positives.  In general all extensions
+that set properties or call methods except :php:`formAction()` are affected.
+
+
+Migration
+=========
+
+In general, extensions should not instantiate and re-use controllers of the core. Existing
+usages should be rewritten to be free of calls like these.
