If you would like to transfer a domain name from one domain name registrar to another, you will need to pass through a few safety steps. One of them is getting a unique EPP authorization code from the present registrar – as long as you are the domain registrant, since the code is emailed to the domain owner’s mailbox and no one else can obtain it. You’ll have to provide this code to the new domain registrar, otherwise they will not be able to initiate the domain name transfer procedure. The EPP authorization 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 security measure, the transfer code for a domain may be changed on a regular basis. Some registrar companies call this code a domain password, a domain secret or an Auth key as well.
