For Chrome on desktop OS, it will popup a QR code that you can scan it by passkey-registered phone like[1].

If your desktop/laptop has TPM, TrustZone or other similar devices, it can register Passkey too.

That’s interesting and I think potentially addresses the concern. I don’t think I’ve seen Apple have a QR scanning code option for passcodes but it’s possible that’s just integrated into normal QR in-camera. Apple doesn’t have a QR export does it?

What would be nicer if there’s a way to do this in Chrome on mobile. I’m not always near a computer although I’m reality that’s probably when I’d be adding the passkey via chrome.

Exactly — I just did this, and it's that simple.

You transferred a passkey from chrome to iOS?

In my case I created (1) one passkey for the Apple ecosystem, and (2) a second passkey for Chrome. I had to add the Chrome-specific passkey because Google isn't using native OS passkey support via Keychain.

I don't know if this will be universally true among sites that support passkeys, but Google allows you to create multiple passkeys per account.
