If you decide to transfer a domain name from one company to another, you will need to pass through several safety steps. One of them is getting a unique EPP authentication code from the present registrar company – on the condition that you are the registrant, since the code is emailed to the domain owner’s mailbox and no one else can see it. You will have to give this code to the new domain registrar, or else they won’t be able to begin the transfer process. The EPP codes are case-sensitive and may comprise of digits 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 security measure, the transfer authorization code for a domain name may be altered regularly. Certain domain registrars call this code a domain password, a domain secret or an Auth key as well.
