CheckUser currently integrates with the CentralAuth extension such that the wiki specified in $wgCentralAuthLoginWiki has account creation logs in the CheckUser results for all accounts created on any wiki in the wikifarm.
This in effect creates a minimal Global CheckUser and is used on WMF projects to find accounts cross-wiki for LTAs (long term abusers).
Client Hints data should be collected and displayed for these events for the wiki specified in $wgCentralAuthLoginWiki so that Client Hints data can be used to compare accounts on that wiki.
Acceptance criteria
- Account creations shown in the $wgCentralAuthLoginWiki wiki CheckUser results have Client Hints data specified.
