If you decide to transfer a domain from one company to another, you will have to pass 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 domain registrant, since the code is sent to the owner's email and no one else can see it. You have to give this code to the new domain registrar, or else they won’t be able to initiate the transfer process. The EPP codes are case-sensitive and may contain digits or special characters such as dots or commas, which can be easily mistyped, so make sure you copy and paste the right code. As an additional safety measure, the transfer authorization code for a domain may be reset on a regular basis. Some registrars call this code a domain password, a domain secret or an Auth key as well.
