# Deprecation: #85555 - TypoScriptFrontendController->getUniqueId

See [forge#85555](https://forge.typo3.org/issues/85555)

## Description

The unused method `TYPO3\CMS\Frontend\Controller\TypoScriptFrontendController->getUniqueId()` has been marked as
deprecated.

## Impact

Calling the method directly will trigger a PHP `E_USER_DEPRECATED` error.

## Affected Installations

TYPO3 installations with custom extensions calling this public method directly.

## Migration

It is recommended to build a fully unique string functionality in a separate PHP class, if needed, decorated
with a proper singleton pattern, or a runtime cache.
