If you would like to transfer a domain from one registrar company to another, you’ll have to go through a couple of security steps. One of them is obtaining a special EPP code from the present registrar company – as long as you are the registrant, since the code is sent to the owner's email account and no one else can obtain it. You have to provide this code to the new domain name registrar, or else they won’t be able to start the transfer process. The EPP authentication codes are case-sensitive and may include digits or special characters such as dots or commas, which can be easily mistyped, 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 regularly. Certain companies call this code a domain password, a domain secret or an Auth key as well.
