If you would like to transfer a domain name from one registrar to another, you’ll need to go through a few safety procedures. One of them is getting a special EPP authentication code from the current registrar company – as long as you are the registrant, since the code is emailed to the owner's email account and nobody else can obtain it. You will need to provide this code to the new registrar company, otherwise they won’t be able to start the domain transfer process. The EPP codes are case-sensitive and may contain digits or special characters such as dots or commas, which can be easily miswritten, so make sure you copy/paste the right code. As an additional security measure, the transfer authorization code for a domain name may be reset regularly. Certain domain name registrars call this code a domain password, a domain secret or an Auth key as well.
