If you want to transfer a domain from one domain name registrar to another, you’ll need to go through a couple of security steps. One of them is getting a special EPP authorization code from the current domain registrar – as long as you are the domain registrant, since the code is sent to the domain owner’s mailbox and nobody else can see it. You’ll have to give this code to the new domain name registrar, otherwise they won’t be able to begin the domain name transfer procedure. The EPP authorization codes are case-sensitive and may include digits or special characters such as commas or dots, which can be easily mistyped, so make sure you copy and paste the correct code. As an extra safety measure, the transfer authorization code for a domain may be reset regularly. Some registrars refer to this code as a domain secret, an Auth key or a domain password as well.
