If you wish to transfer a domain from one registrar to another, you will have to go through a couple of security procedures. One of them is getting a special EPP code from the present domain name registrar – provided that you are the domain registrant, since the code is emailed to the domain owner’s email address and no one else can see it. You will have to give this code to the new registrar company, or else they won’t be able to start the transfer procedure. The EPP codes are case-sensitive and may comprise of numbers or special characters such as dots or commas, which can be easily miswritten, so make sure you copy and paste the right code. As an extra protection measure, the transfer authorization code for a domain name may be reset regularly. Certain domain registrars refer to this code as a domain secret, an Auth key or a domain password as well.
