Reason:
The CryoKey has not received any code update for the last 5 years beside the usual robot maintenance. It seems to be a system with a hardware key for authentication.
https://wikiapiary.com/wiki/Extension:CryoKey shows only one public deployment. It is the company wiki and is at version 1.20.
The extension has not been updated to use AuthManager introduced in MediaWiki 1.27: T110452
