If you wish to transfer a domain name from one domain registrar to another, you will have to go through a couple of safety procedures. One of them is getting a unique EPP code from the present registrar company – provided that you are the registrant, since the code is emailed to the owner's mailbox and nobody else can see it. You need to provide this code to the new domain name registrar, otherwise they won’t be able to initiate the transfer procedure. The EPP authentication codes are case-sensitive and may include digits or special symbols such as dots or commas, which can be easily misentered, so make sure you copy and paste the correct code. As an extra security measure, the transfer authorization code for a domain name may be reset regularly. Certain registrar companies call this code an Auth key, a domain secret or a domain password as well.
