If you’d like to transfer a domain from one registrar to another, you’ll need to go through a few safety procedures. One of them is getting a special EPP authorization code from the present domain registrar – provided that you are the registrant, since the code is sent to the owner's email address and nobody else can see it. You need to provide this code to the new registrar, or else they will not be able to initiate the domain transfer process. The EPP codes are case-sensitive and may include numbers or special characters such as commas or dots, which can be easily miswritten, so make sure you copy/paste the right code. As an extra protection measure, the transfer code for a domain name may be changed on a regular basis. Certain registrars refer to this code as a domain secret, an Auth key or a domain password as well.
