While I would agree this sounds more secure, I'm always worried about people getting further locked in to Google's products.
Hopefully this system won't take accounts "hostage" by requiring you use Chrome to log in to them, but it's Google, so...
EDIT: I'm wrong, passkeys are stored per-device and can be shared between devices using an open standard. Here's a video explaining the basics. It addresses my concern at around the 2:50 mark.
Use a yubikey, that doesn’t vendor-lock you to an OS ecosystem. They make one with nfc so it’s not a pain to use with your phone.
I'm not sure if this is universal or specific to the last site I tried to use my Yubikey with as a passkey, but it only would allow it to be used as 2FA, not actual passwordless authentication.
I assume this is because Yubikeys don't create a secret for each individual website I suppose? Not exactly sure about that one.
Both the website and your physical security token must support the right type of webauthn credentials (the token has storage for a certain number of slots with "discoverable credentials").
Passkeys is a variant of the same which is bound to your device's own TPM / SE security chip or equivalent, plus a synchronization feature for backups.
