Someone on slashdot correctly pointed out that these are only single factor on the server end. You enter a pin to unlock the device, the server can check if the device says you unlocked it, but there is no sending a second factor to the server. If a device was hacked to get the keys, or just says to the server that you presented a pin but didn’t really, the server has no clue. Passkey + TOTP would be multi factor on the server side.
