If you decide to transfer a domain name from one domain registrar to another, you will have to go through a couple of safety procedures. One of them is obtaining a unique EPP authorization code from the current registrar – provided that you are the domain registrant, since the code is emailed to the domain owner’s email address and nobody else can obtain it. You have to provide this code to the new domain registrar, otherwise they will not be able to start the domain name transfer. The EPP authorization codes are case-sensitive and may contain numbers or special symbols such as dots or commas, which can be easily mistyped, so make sure you copy and paste the correct code. As an additional security measure, the transfer authorization code for a domain name may be changed regularly. Some registrar companies refer to this code as a domain secret, an Auth key or a domain password as well.
