Passkeys replace passwords with encrypted key pairs that can’t be phished or leaked. Learn how FIDO2 and WebAuthn work, their pros and flaws.

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

    Passkeys are a technology that were surpassed 10 years before their introduction

    Question is by what? I could see an argument that it is an overcomplication of some ill-defined application of x509 certificates or ssh user keys, but roughly they all are comparable fundamental technologies.

    The biggest gripe to me is that they are too fussy about when they are allowed and how they are stored rather than leaving it up to the user. You want to use a passkey to a site that you manually trusted? Tough, not allowed. You want to use against an IP address, even if that IP address has a valid certificate? Tough, not allowed.
