Considering many services only allow one YubiKey or only one TOTP authenticator ... I might actually need a short term solution like this to beat the 2FA on those services. Otherwise what happens if I lose my key on the road?
The 2FA services that allow >1 YubiKey are good, I can have a backup key locked up some place and use them as intended.
