If you’d like to transfer a domain from one registrar to another, you’ll have to pass through a couple of security steps. One of them is getting a unique EPP authorization code from the present registrar – as long as you are the domain registrant, since the code is sent to the domain owner’s email account and nobody else can get it. You will have to give this code to the new registrar, otherwise they won’t be able to initiate the domain transfer. The EPP authorization codes are case-sensitive and may comprise of numbers or special symbols such as dots or commas, which can be easily misentered, so make sure you copy and paste the correct code. As an extra security measure, the transfer authorization code for a domain may be reset on a regular basis. Certain domain name registrars call this code a domain password, a domain secret or an Auth key as well.
