Thanks for the details.

I meant to use Nostr just to do the cross-device stuff, I wasn't think how to generate and store the key in the first place. Maybe something like nostr:npub180cvv07tjdrrgpa0j7j7tmnyl2yr6yr7l8j4s3evf6u64th6gkwsyjh6w6's FROST bunker can help.

But I'm not really sure that passkey's advantages are so strong that it is worthwhile. I should look into it further.

Ah yeah, beyond the un-extractable private key thing and the wide support, there's nothing really special about passkeys.

For cross-device stuff, IMO decentralised TEE cloud is the way to go, over FROST bunkers. Much much better UX. It's like nitro enclaves but decentralised.

We use https://phala.com/dstack for some related things and it's good. The problem there is that many people here will get upset that it uses a blockchain that's not Bitcoin. Even though you need a blockchain to orchestrate the TEEs, and Bitcoin doesn't have the functionality, and nostr clients would only ever interact with the TEEs and not the chain, etc etc.
