If you’d like to transfer a domain name from one registrar company to another, you will have to pass through a few safety procedures. One of them is getting a unique EPP authorization code from the current registrar – as long as you are the registrant, since the code is emailed to the domain owner’s email and no one else can get it. You will have to give this code to the new domain registrar, otherwise they won’t be able to begin the domain name transfer. The EPP codes are case-sensitive and may contain numbers or special symbols such as commas or dots, which can be easily mistyped, so make sure you copy & paste the correct code. As an extra security measure, the transfer authorization code for a domain may be altered regularly. Certain domain name registrars refer to this code as a domain secret, a domain password or an Auth key as well.
