If you would like to transfer a domain name from one registrar to another, you’ll have to go through a couple of safety steps. One of them is getting a unique EPP authorization code from the current domain registrar – provided that you are the registrant, since the code is sent to the owner's email address and no one else can get it. You’ll have to give this code to the new registrar, otherwise they will not be able to start the transfer process. The EPP authentication codes are case-sensitive and may contain numbers or special characters such as commas or dots, which can be easily miswritten, so make sure you copy and paste the right code. As an additional protection measure, the transfer authorization code for a domain name may be changed on a regular basis. Certain registrars refer to this code as a domain password, an Auth key or a domain secret as well.
