Passkeys are built on the FIDO2 standard (CTAP2 + WebAuthn standards). They remove the shared secret, stop phishing at the source, and make credential-stuffing useless.

I broke down how passkeys work, their strengths, and what’s still missing
You know that not every account is only used by a single user, right?
I think that’s the problem right there… If you share accounts across multiple people you have far greater problems than how passkeys work…
Or they’re using it as intended. I’ve had more than one account I’ve gotten by cost sharing with friends. That’s not a problem, that’s a solution.
