If you want to transfer a domain name from one domain name registrar to another, you’ll need to pass through a few security steps. One of them is getting a unique EPP code from the present registrar company – provided that you are the registrant, since the code is emailed to the owner's email account and no one else can see it. You will need to give this code to the new registrar, otherwise they won’t be able to initiate the domain name transfer procedure. The EPP authentication codes are case-sensitive and may contain numbers or special characters such as commas or dots, which can be easily misentered, so make sure you copy and paste the right code. As an extra security measure, the transfer code for a domain may be changed regularly. Some domain registrars call this code a domain secret, an Auth key or a domain password as well.
