If you wish to transfer a domain name from one domain registrar to another, you will have to go through several safety procedures. One of them is obtaining a special EPP code from the present domain registrar – provided that you are the registrant, since the code is emailed to the owner's email and nobody else can see it. You’ll have to provide this code to the new domain name registrar, or else they will not be able to begin the domain transfer procedure. The EPP codes are case-sensitive and may include numbers or special symbols such as commas or dots, which can be easily misentered, so make sure you copy/paste the right code. As an extra protection measure, the transfer authorization code for a domain name may be altered regularly. Some domain name registrars refer to this code as a domain password, an Auth key or a domain secret as well.
