If you decide to transfer a domain name from one domain name registrar to another, you will need to go through several security procedures. One of them is obtaining a unique EPP authentication code from the present registrar – on the condition that you are the domain registrant, since the code is emailed to the domain owner’s email address and no one else can obtain it. You will need to give this code to the new domain name registrar, otherwise they won’t be able to start the domain name transfer. The EPP codes are case-sensitive and may comprise of digits or special characters such as dots or commas, which can be easily miswritten, so make sure you copy and paste the right code. As an extra safety measure, the transfer authorization code for a domain may be reset regularly. Some domain registrars refer to this code as a domain password, an Auth key or a domain secret as well.
