If you wish to transfer a domain name from one domain registrar to another, you’ll have to pass through a couple of safety procedures. One of them is getting a unique EPP authentication code from the current domain name registrar – as long as you are the domain registrant, since the code is sent to the domain owner’s email and no one else can obtain it. You will have to provide this code to the new registrar company, or else they will not be able to initiate the domain transfer procedure. The EPP authorization codes are case-sensitive and may include numbers or special symbols such as dots or commas, which can be easily misentered, so make sure you copy & paste the right code. As an additional security measure, the transfer authorization 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.
