If you would like to transfer a domain from one domain registrar to another, you’ll have to go through a couple of safety procedures. One of them is obtaining a unique EPP authentication code from the current registrar – as long as you are the domain registrant, since the code is sent to the owner's email address and no one else can get it. You’ll need to provide this code to the new registrar company, or else they will not be able to initiate the domain name transfer. The EPP codes are case-sensitive and may comprise of numbers or special symbols such as commas or dots, which can be easily miswritten, so make sure you copy and paste the correct code. As an extra security measure, the transfer code for a domain may be changed on a regular basis. Certain domain name registrars refer to this code as a domain password, an Auth key or a domain secret as well.
