One aspect of FIDO that could still be troublesome is account recovery in case of inadvertent loss of passkey. I think the idea is that passkeys are synced between devices, see e.g.: https://developer.apple.com/videos/play/wwdc2021/10106/ https://developer.apple.com/videos/play/wwdc2021/10106/ I haven't look deeply into passkey enough yet, but aren't we replacing "what if I lose by device" by "what if company XYZ decides to nuke my access to my synchronized passkey"?
