If you’d like to transfer a domain from one domain registrar to another, you will have to pass through a couple of safety steps. One of them is getting a special EPP authentication code from the present domain name registrar – on the condition that you are the domain registrant, since the code is emailed to the domain owner’s email address and nobody else can see it. You’ll need to provide this code to the new domain registrar, otherwise they won’t be able to start the transfer process. The EPP authentication codes are case-sensitive and may contain digits or special symbols such as commas or dots, which can be easily miswritten, so make sure you copy and paste the right code. As an additional protection measure, the transfer authorization code for a domain may be altered regularly. Some registrar companies call this code a domain password, a domain secret or an Auth key as well.
