If you want to transfer a domain from one domain name registrar to another, you will need to pass through a few security procedures. One of them is obtaining a unique EPP code from the current registrar – as long as you are the registrant, since the code is sent to the domain owner’s email account and no one else can get it. You will need to provide this code to the new domain name registrar, or else they won’t be able to initiate the transfer. The EPP codes are case-sensitive and may include numbers or special symbols such as dots or commas, which can be easily misentered, so make sure you copy/paste the right code. As an extra security measure, the transfer code for a domain may be changed on a regular basis. Certain registrars refer to this code as a domain password, a domain secret or an Auth key as well.
