If you would like to transfer a domain name from one domain registrar to another, you’ll need to go through several safety steps. One of them is getting a special EPP authentication code from the current registrar company – on the condition that you are the domain registrant, since the code is sent to the owner's email address and nobody else can see it. You’ll need to give this code to the new registrar company, otherwise they will not be able to initiate the transfer. The EPP authorization codes are case-sensitive and may include digits or special characters such as commas or dots, which can be easily mistyped, so make sure you copy/paste the correct code. As an additional protection measure, the transfer code for a domain may be changed regularly. Certain registrars call this code a domain secret, a domain password or an Auth key as well.
