@cosohelp If I want to set up a second Yubikey device (backup) with my CoSo account I assume the easiest way is to deactivate my existing Yubikey and set up both #Yubikeys at same time to sync secret key/QR code? I did not copy the secret key at time of original setup. #MFA #2FA

@bfgreen Yep. That would work. If you're fast enough.

@th3j35t3r LOL speed doesn't matter if I have the original secret key seed from the QR I can add to multiple HW keys at leisure. Ask me how I know (as you like to say!)
