If you want to transfer a domain name from one company to another, you will have to go through a couple of security procedures. One of them is getting a special EPP authorization code from the current registrar company – on the condition that you are the registrant, since the code is sent to the domain owner’s email address and nobody else can obtain it. You will have to provide this code to the new registrar company, otherwise they will not be able to begin the domain transfer process. The EPP authorization codes are case-sensitive and may contain digits or special characters such as dots or commas, which can be easily miswritten, so make sure you copy and paste the right code. As an extra safety measure, the transfer code for a domain name may be reset regularly. Certain domain registrars refer to this code as an Auth key, a domain secret or a domain password as well.
