I think remembering some kind of no-no regarding something, not Foss or such, regarding Grafana? I might be mixing up things, I am honesty unsure, sry for that.

Probs to OP though.

Good take. I trust you on this, if you mind me asking: What is now the alternative? A system of setting up once, let it work until hardware dies etc.

Every way is a security risk in itself. For example if my home burns down I lose x% of the ways. y% can potentially break. z% can potentially be lost to my stupidity. What if I get in a car accident and hit my head and get amnesia and forget a mandatory password: for these cases there are different retrieval strategies, but obviously are ‘stressful’ to set up to stay relatively secure. What can I say, these are the thoughts I have about this topic.

FIDO2 is great. Only thing I am scared of is losing it/them. So a backup access becomes the issue IMHO.
