Passkeys Explained: The End of Passwords (sentientrant.com)

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

This is a fundamental misunderstanding of how the FIDO2 standard works. It is not designed to be vendor specific and as other people in this thread point out, plenty of open-source secrets managers and hardware implement passkeys.

What we've seen is the typical Silicon Valley model of "embrace, extend, extinguish" so you're right to be wary of any implementation by Google or Microsoft.

Same goes for biometrics - how you unlock the passkey isn't specified in the standard. It is left up to the implementation. If you don't want to use biometrics, you don't have to.
