If you’d like to transfer a domain from one domain registrar to another, you will have to pass through a couple of safety procedures. One of them is getting a special EPP code from the present registrar – as long as you are the registrant, since the code is sent to the owner's email address and no one else can get it. You need to provide this code to the new registrar, otherwise they will not be able to initiate the domain name transfer. The EPP authentication codes are case-sensitive and may comprise of numbers or special symbols such as dots or commas, which can be easily misentered, so make sure you copy and paste the right code. As an extra security measure, the transfer authorization code for a domain name may be altered regularly. Some companies refer to this code as an Auth key, a domain secret or a domain password as well.
