I changed the email address associated with my 1P account and with this one must sign back in with all devices. So as expected with my phone I was prompted for my hardware key which I 'swiped' but unlike for any other account where I use my yubikey I got this screen.
(Initially there was an actual "captured string"...this pic is from "History")
