Passkeys are technically more secure than most bitcoin wallets rn. Very cool stuff. Do check it out! passkeys.dev has a demo as well that you can try. They’re designed to replace passwords as an authentication mechanism. 

Thank you for the explanation and the link. I wasn't aware of the technology, nor the development.
Off to study that for a bit.

Passkeys, the marketing term for WebAuthn’s discoverable credentials feature. Or whatever they’re calling it now (it’s changed at least once or twice in the spec). https://passkeys.dev/docs/reference/specs/

Passkeys are very different from scanning your face and doing facial recognition. It uses local device capabilities like Windows Hello, Face ID etc to hold an elliptical private key securely on a security chip then sign a challenge given by the server. It’s basically LNURL, but better (cross device goes over Bluetooth instead of internet). Both are pretty awesome tho!!
