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
How many good passwords can you memorize? I can maintain 2-3 in my head long term, especially if only used rarely, and you can be phished if you are typing it in. Not tenable for online accounts. The only real comparison with security parity is a password manager + 2fa generated on-device, compared with passkeys. In both cases, you have “strong” password, no re-use, resiliency to fishing, and requires both “something you know and something you have.” I think a password manager is slightly more usable, but I’m not convinced either is a “good” experience yet.
This experience works perfectly for me. I have no need of whatever junk the latest consortium of megacorps has come up with.
