+===============================================================
+Deprecation: #84980 - BackendUserAuthentication->addTScomment()
+===============================================================
+
+See :issue:`84980`
+
+Description
+===========
+
+Method :php:`TYPO3\CMS\Core\Authentication\BackendUserAuthentication->addTScomment()` has been marked as deprecated.
+
+
+Impact
+======
+
+The method has been used to add comments to :typoscript:`TSconfig` at runtime, those
+comments however are never shown in the TYPO3 backend.
+Calling the method directly will trigger a PHP :php:`E_USER_DEPRECATED` error.
+
+
+Affected Installations
+======================
+
+Instances with extensions calling :php:`BackendUserAuthentication->addTScomment()`
+will trigger a deprecation error.
+It is however rather unlikely that extensions
+rely on this widely unknown API method and method calls were mostly core internal.
+The extension scanner should find possible usages within extensions.
+
+
+Migration
+=========
+
+Drop the method call.
