Hey there,
Appologies for the late response, those two variables I got from the dependency that the OpenID plugin uses in Mediawiki called PluggableAuth.

That might of been me barking down the wrong tree, but from what I can gather it seems Cloudron uses OpenID for its authentication, which uses PluggableAuth. Those two variables are what can be custom inputed to change the message I believe.
Appreciate the quick response, thanks for the help.
