If you want to transfer a domain from one registrar company to another, you will need to go through a couple of safety procedures. One of them is getting a special EPP code from the current domain name registrar – on the condition that you are the registrant, since the code is sent to the domain owner’s email and nobody else can get it. You’ll have to provide this code to the new registrar, or else they will not be able to initiate the domain name transfer. The EPP authentication codes are case-sensitive and may contain numbers or special symbols such as dots or commas, which can be easily mistyped, 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 on a regular basis. Certain registrars refer to this code as a domain secret, a domain password or an Auth key as well.
