Thats because the people behind passkeys are paternalistic and don't trust users. I had an argument with one of them a few months ago.

My read on it all is that FIDO is stuck in some sort of groupthink. They don't feel the boots on the ground confusion around passkeys being opaque. They only care about phishing and being called "insecure" and don't care about anything else. Hence why WebAuthn has additional weird anti features like AAGUID for provider authentication.

Another one of those ridiculous threads is saying you gotta have support for nonsense like user presence verification.

To be fair, trusting users with passwords/credentials is how we got into the mess of phishing et al in the first place.

The phishing resistance on fake websites is largely a function of the fact its an ssh key and you can't man in the middle those after first setup because you have known_hosts, which in the case of passkeys gets replaced with the website certificate technology.

The baking in "which authenticator is storing this passkey" and "require user to provide biometrics/pin to verify presence for this passkey" and "don't make it easy or possible to export passkeys" behaviour is more just control.

I guess it sort of helps if the threat model is complete remote code execution inside the victims brain because you got them to export their keys to you, but it seems more useful for websites and governments whitelisting what hardware and software they deem acceptable.

Reminder that Facebook has warnings and prevention mechanisms to avoid users pasting malicious JavaScript into the console on Facebook.com (which would exfiltrate session cookies). Preventing users from accessing these keys directly makes sense!
