If you would like to transfer a domain from one domain name registrar to another, you will have to pass through several safety steps. One of them is obtaining a unique EPP code from the current domain name registrar – as long as you are the domain registrant, since the code is sent to the owner's email and nobody else can obtain it. You need to give this code to the new registrar company, or else they will not be able to initiate the domain name transfer procedure. The EPP authentication codes are case-sensitive and may contain numbers or special symbols such as commas or dots, which can be easily misentered, so make sure you copy & paste the correct code. As an extra protection measure, the transfer authorization code for a domain name may be altered on a regular basis. Certain registrars call this code a domain secret, a domain password or an Auth key as well.
