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



Isn’t that the same thing? All my credentials & passkeys are in the cross-platform password manager available from all my devices & any web browser. Passkeys even have a cross-device flow, so we can just scan a QR code & use a phone to sign into anything.
Manually keying in a password just feels so boomer.
Not at all the same. I can type or dictate my passwords on any device with a keyboard. I am not reliant on an individual device continuing to work. In fact I could get all new devices tomorrow, with no access to any previous device, and log into all my accounts within minutes.
Passkeys do not allow, and specifically prevent, that.
Exactly the same with a password manager which stores passkeys. Are you reading before responding?
