We finally released an update to our 2 factor security which I know many people have been asking for. You can now add a backup besides your phone to receive the codes such as an app like Google Authenticator. You can now set the 2fa up for the whole account or just high risk transactions such as, changes to your password or PIN.
If you want all the details we have an article here https://www.godaddy.com/help/enable-two-step-verification-7502
