After @blacklight447 asked about my opinion on #OnlyKey, I looked at their docs once more.
I remembered that they didn't convince me last time, I saw them, but I took the time now to write down a short analysis of what I figured out from their docs about the security status of this "Hardware password manager".

I really hope they proof me wrong, otherwise, it's a dumpster fire.
