question Is there a need to redact the URL? The URL is currently a part of the config entry's title/display name, so this should already be "public"

[strawgate]

I was a little worried about having the URL and the fact that there is no authentication in the same diagnostic message but I'll take another look at this and remove the URL for now

Is this PR still valid?
