If you want to transfer a domain name from one domain registrar to another, you’ll have to go through a few security steps. One of them is obtaining a special EPP authentication code from the present registrar – on the condition that you are the domain registrant, since the code is sent to the domain owner’s email and no one else can obtain it. You have to give this code to the new registrar company, otherwise they will not be able to begin the domain name transfer procedure. The EPP authentication codes are case-sensitive and may comprise of numbers or special characters such as commas or dots, which can be easily misentered, so make sure you copy and paste the correct code. As an additional protection measure, the transfer code for a domain name may be changed on a regular basis. Some registrar companies refer to this code as a domain secret, a domain password or an Auth key as well.
