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.
But adoption is still low, and interoperability between Apple, Google, and Microsoft isn’t seamless.
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.
And it only takes one person with a grudge to cause a problem. I have seen it. I have shared accounts but very carefully and if someone abuses it then they permanently lose access to my stuff even if they are family.
