If you would like to transfer a domain from one registrar company to another, you will have to go through several safety steps. One of them is getting a unique EPP authorization code from the present registrar company – as long as you are the registrant, since the code is sent to the owner's email address and nobody else can see it. You will have to provide this code to the new registrar, otherwise they won’t be able to begin the domain transfer procedure. The EPP authentication codes are case-sensitive and may contain digits or special characters such as commas or dots, which can be easily miswritten, so make sure you copy and paste the correct code. As an additional safety measure, the transfer code for a domain name may be altered regularly. Certain domain registrars refer to this code as a domain secret, a domain password or an Auth key as well.
