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

I think most passkey implementations incorporate multiple factors already. The session factor is considered distinct from the device factor, even if it’s all on the same device.

Which isn’t super different from the traditional USB key procedure, where a user would activate a FIDO biometric after clearing an SSO portal, or what have you.
