Ah, interesting - genuinely curious: Assumption: You're abroad, with your Yubikey, in some weird scenario you either lose or break your Yubikey. You're supposed to access your accounts for the rest of your stay, what is the solution here? Or do you bring multiple keys with you and just grab another one from your suitcase? I'm curious about a realistic (not extreme) scenario where a key breaks or gets lost, with the physical backup key not being within reach. Do the backup keys often need to be synced in some way and kept updated? I use 1Password with a backup at a trusted location, that can be sent digitally to me (but it also in the cloud), and all I need to get into my accounts is the password to recover if my laptop gets stolen or breaks. I wonder if what you say is the only way to make Yubikey work in a travel scenario, to just have multiples of them with you, or if I am grossly misunderstanding it, still.
