If you’d like to transfer a domain name from one domain registrar to another, you will need to go through several safety steps. One of them is getting a unique EPP authorization code from the current registrar – provided that you are the domain registrant, since the code is sent to the domain owner’s email address and no one else can obtain it. You will have to provide this code to the new domain name registrar, or else they won’t be able to begin the transfer process. The EPP authorization codes are case-sensitive and may include digits or special symbols such as dots or commas, which can be easily mistyped, so make sure you copy & paste the right code. As an additional protection measure, the transfer code for a domain may be changed regularly. Certain domain registrars refer to this code as an Auth key, a domain secret or a domain password as well.
