If you decide to transfer a domain name from one company to another, you’ll need to go through a couple of safety procedures. One of them is getting a unique EPP authentication code from the current domain registrar – provided that you are the registrant, since the code is emailed to the domain owner’s email and no one else can see it. You will need to give this code to the new domain registrar, otherwise they will not be able to begin the domain name transfer. The EPP authentication codes are case-sensitive and may comprise of digits or special symbols such as commas or dots, which can be easily mistyped, 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 regularly. Some companies call this code a domain password, a domain secret or an Auth key as well.
