Passkeys replace passwords with encrypted key pairs that can’t be phished or leaked. Learn how FIDO2 and WebAuthn work, their pros and flaws.

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

    Every time I was prompted to use one by plugging my phone in to my computer nothing happened. That was a little over a year ago.

      It’s been a very seamless experience with Bitwarden. Pretty much “click passkey, now logged in”.

        I mean when I was trying to set one up. I wasn’t ever prompted to use a password manager. It just said to plug my phone into my computer. I did. And it didn’t detect anything. With user experience in setup that poor I don’t trust them yet.

            I don’t know what to tell you. Multiple sites and services asked if I wanted to set up a passkey, every time I got prompted to plug my phone in via USB, and nothing happened when I did. At no point in the process did it give me a QR code or ask me if I wanted to set one up through a password manager instead of a phone. I didn’t do anything special or incorrect. I followed the normal prompts they gave me.
