If you decide to transfer a domain name from one domain registrar to another, you will have to go through a few security procedures. One of them is obtaining a unique EPP authorization code from the current registrar – provided that you are the registrant, since the code is sent to the domain owner’s email and no one else can see it. You will need to provide this code to the new registrar company, otherwise they won’t be able to start the domain transfer process. The EPP authorization codes are case-sensitive and may include numbers or special symbols such as commas or dots, which can be easily misentered, 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 altered on a regular basis. Some domain name registrars call this code a domain password, an Auth key or a domain secret as well.
