Feature Request: add `note on OTP` link to config dialog

[juchem]

General information

The config dialog states that enabling OTP is not recommended with no explanation of why, which can be quite confusing (e.g.: is OTP not recommended or what?).

The github repo has a very nice and informative note about why that is the case, but one has to know about it to look for it. It took me a long time to find that note out.

What should happen?

This is a feature request to add a link to the note on OTP (perhaps on the not recommended text) to the config dialog, for easier discoverability. Bonus points if hoving over it gives out a brief explanation, suggesting the link for further info.
