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
What are using lol? I have never been asked to plug in my phone to a computer. I have use Bitwarden and KeepassXC and also used my phone to scan the QR in chromium browsers for passkeys and it just worked in all the browsers flawlessly (even ungoogled chromium). I just want Linux Distros to allow setup a default password manager for the user and implement passkeys auth mechanism for the apps installed in the device.
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.
