Who Needs a Fallback Key?

Are you among the few people that did not register your EOS? or Have you registered but the key was rejected? In these two cases, the fallback mechanism will apply. For the people who have registered correctly, these steps do not apply to you. You just have to use the Private Key associated with your EOS Public Key that you used for registration.
