If you decide to transfer a domain name from one company to another, you will have to go through several safety procedures. One of them is getting a unique EPP authorization code from the present domain registrar – on the condition that you are the domain registrant, since the code is sent to the domain owner’s email account and no one else can get it. You have to provide this code to the new domain name registrar, otherwise they will not be able to start the domain transfer. The EPP authorization codes are case-sensitive and may include digits 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 additional security measure, the transfer authorization code for a domain name may be reset on a regular basis. Certain domain registrars call this code a domain password, a domain secret or an Auth key as well.
