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

Technically they are the 2fa. The second factor is something you have. I store all my passkeys in my password manager too, so I'm not faulting you, but technically that's just undoing the second factor, because now my two factors are "two things that are both unlocked by the same one thing I know". Which is one complicated factor spread across two form fields.
