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



Password managers store passkeys. They’re portable and not device-locked. Been using them on Bitwarden for like 2 years now.
It is not portable in the sense that you need bitwarden installed on the device you are trying to connect from.
Passwords can be plain text, which means I can copy, paste, and dictate them to a device that does not have additional software installed.
