If you would like to transfer a domain from one company to another, you’ll need to go through a couple of safety steps. One of them is obtaining a unique EPP authentication code from the present registrar – as long as you are the registrant, since the code is emailed to the owner's mailbox and nobody else can obtain it. You’ll have to provide this code to the new registrar, or else they won’t be able to start the transfer process. The EPP authorization codes are case-sensitive and may include numbers or special symbols such as dots or commas, which can be easily mistyped, so make sure you copy and paste the correct code. As an extra security measure, the transfer code for a domain name may be reset on a regular basis. Certain domain registrars call this code an Auth key, a domain password or a domain secret as well.
