If you want to transfer a domain from one registrar to another, you will have to pass through a couple of security steps. One of them is getting a unique EPP code from the current domain name registrar – as long as you are the registrant, since the code is sent to the domain owner’s email account and nobody else can see it. You’ll have to provide this code to the new registrar company, otherwise they won’t be able to begin the domain transfer process. The EPP codes are case-sensitive and may comprise of 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 authorization code for a domain may be reset on a regular basis. Certain registrar companies call this code a domain password, an Auth key or a domain secret as well.
