If you want to transfer a domain name from one domain registrar to another, you will need to pass through several safety procedures. One of them is getting a unique EPP authorization code from the current registrar – on the condition that you are the registrant, since the code is emailed to the domain owner’s email and no one else can get it. You have to give this code to the new registrar company, otherwise they will not be able to start the domain transfer process. The EPP codes are case-sensitive and may include numbers or special symbols such as dots or commas, which can be easily miswritten, so make sure you copy and paste the correct code. As an additional protection measure, the transfer authorization code for a domain name may be reset regularly. Some domain name registrars refer to this code as an Auth key, a domain password or a domain secret as well.
