If you wish to transfer a domain name from one registrar to another, you will have to pass through several safety steps. One of them is obtaining a unique EPP authentication code from the current domain name registrar – provided that you are the domain registrant, since the code is emailed to the domain owner’s email and nobody else can obtain it. You will need to provide this code to the new domain name registrar, or else they will not be able to initiate the transfer procedure. The EPP codes are case-sensitive and may contain digits or special characters such as commas or dots, which can be easily misentered, so make sure you copy & paste the right code. As an extra safety measure, the transfer code for a domain may be altered on a regular basis. Some domain registrars call this code an Auth key, a domain password or a domain secret as well.
