If you want to transfer a domain from one domain registrar to another, you’ll have to pass through several security procedures. One of them is obtaining a special EPP authentication code from the present registrar company – on the condition that you are the registrant, since the code is emailed to the owner's email address and nobody else can get it. You will need to give this code to the new registrar company, or else they will not be able to initiate the transfer process. The EPP codes are case-sensitive and may include digits or special characters such as commas or dots, which can be easily misentered, so make sure you copy and paste the correct code. As an extra safety measure, the transfer code for a domain name may be reset on a regular basis. Certain domain registrars refer to this code as a domain secret, an Auth key or a domain password as well.
