If you wish to transfer a domain name from one company to another, you’ll need to pass through a couple of security steps. One of them is getting a unique EPP code from the current registrar company – as long as you are the registrant, since the code is sent to the owner's mailbox and no one else can obtain it. You’ll have to give this code to the new registrar, otherwise they will not be able to begin the transfer process. The EPP authorization 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 security measure, the transfer authorization code for a domain name may be changed on a regular basis. Certain domain registrars call this code a domain secret, an Auth key or a domain password as well.
