TUSC

From Meta, a Wikimedia project coordination wiki

The Toolserver User Screening Control (TUSC, toollabs:tusc) is a tool to allow users from Wikimedia projects (Wikipedia, Commons, etc.) to perform content-altering actions via web tools hosted on the toolserver. This is necessary because toolserver-based tools are forbidden by policy to ask for the actual Wikipedia/Commons password; instead, you can get a new password for use on the toolserver.
