If you would like to transfer a domain name from one domain name registrar to another, you’ll need to pass through a couple of safety steps. One of them is getting a special EPP authentication code from the present domain name registrar – as long as you are the domain registrant, since the code is emailed to the owner's email account and no one else can obtain it. You’ll have to give this code to the new registrar, otherwise they will not be able to begin the transfer. The EPP authentication codes are case-sensitive and may include numbers or special characters such as dots or commas, which can be easily misentered, so make sure you copy & paste the right code. As an additional protection measure, the transfer authorization code for a domain may be altered on a regular basis. Some registrars refer to this code as a domain secret, an Auth key or a domain password as well.
