Passkeys are deliberately designed to avoid the issues with Bluetooth pairing. This is why a QR code needs to be scanned - devices do not need to be paired.

Not all browsers do passkeys.

When I visit https://webauthn.io/ using Chrome on my mac laptop, it pops up a bluetooth connection. Firefox asks me to connect a device or cancel.

On Windows, Chrome and Edge gives me a QR code. Firefox triggers a Windows security popup.

Inconsistency is the only constant so far.
