The whole thing is great, but for me 3:50 is where you can really pick up the whole vibe in just about a minute. Particularly the perfectly respectful way of handling not knowing how to pronounce someone’s name. And then lapsing into a hallucinogenic zone out time.
Unfortunately, I think you’re going to run into trouble because fido authenticators are geared towards working as user authenticators rather than as device authenticators.
It certainly should be possible from a technical perspective, but implementation-wise, it’s very likely that the code focuses on making fido devices work with client keys, and using tpms for host keys, since that’s much more focused on headless server functionality.
Oval peg in a round hole.
