If you want to transfer a domain name from one registrar to another, you’ll have to go through several safety procedures. One of them is getting a special EPP authentication code from the present registrar – on the condition that 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 need to provide this code to the new registrar company, or else they will not be able to begin the domain transfer. The EPP authorization codes are case-sensitive and may include digits or special characters such as commas or dots, which can be easily miswritten, so make sure you copy/paste the right code. As an extra safety measure, the transfer authorization code for a domain name may be altered regularly. Certain registrar companies call this code a domain secret, an Auth key or a domain password as well.
