If you’d like to transfer a domain name from one domain registrar to another, you will have to pass through several safety procedures. One of them is getting a unique EPP authentication code from the current registrar company – as long as you are the registrant, since the code is sent to the owner's email and nobody else can obtain it. You have to provide this code to the new registrar, or else they will not be able to initiate the domain name transfer procedure. The EPP codes are case-sensitive and may include numbers or special characters such as dots or commas, which can be easily miswritten, so make sure you copy and paste the right code. As an extra safety measure, the transfer authorization code for a domain name may be changed on a regular basis. Certain registrars call this code a domain password, an Auth key or a domain secret as well.
