My Solokey is hackable and firmware available under Apache/MIT (https://github.com/solokeys/solo1).

Unfortunately the easiest way to "export" is likely to rely on the RP, as if they effectively use the sign_counter they may flag such a key as cloned. They should ideally just let you register multiple (and that's an RFC 'SHOULD').

Not a shill by the way, just a happy solokey owner.
