If you’d like to transfer a domain from one domain name registrar to another, you’ll have to go through a few security procedures. One of them is obtaining a unique EPP code from the present domain name registrar – on the condition that you are the domain registrant, since the code is sent to the owner's email address and nobody else can obtain it. You will have to provide this code to the new registrar company, or else they won’t be able to begin the domain transfer process. The EPP authorization codes are case-sensitive and may contain digits or special characters such as dots or commas, which can be easily misentered, so make sure you copy and paste the correct code. As an extra protection measure, the transfer authorization code for a domain name may be reset regularly. Certain domain registrars call this code a domain password, a domain secret or an Auth key as well.
