If you’d like to transfer a domain name from one domain name registrar to another, you will have to pass through a few security steps. One of them is obtaining a unique EPP authorization code from the present domain registrar – on the condition that you are the registrant, since the code is sent to the owner's email address and no one else can see it. You will need to provide this code to the new domain registrar, otherwise they won’t be able to initiate the domain name transfer procedure. The EPP authorization codes are case-sensitive and may contain numbers or special characters such as dots or commas, which can be easily misentered, so make sure you copy/paste the right code. As an extra safety measure, the transfer code for a domain may be changed regularly. Certain registrar companies refer to this code as an Auth key, a domain password or a domain secret as well.
