Passkeys IMO will only work with dedicated U2F/FIFO keys like Yubikeys.

Beware that Passkey storage is limited though and I don't think you can reuse one for multiple sites. My Yubikey 5 NFC stores up to 32 and you should have some redundancy if you ever lose it. You also can't export them. I only use passkeys (in Bitwarden) for things I don't care about.
