If you’d like to transfer a domain from one registrar to another, you will need to pass through a few safety procedures. One of them is obtaining a special EPP code from the present registrar company – provided that you are the registrant, since the code is sent to the owner's email account and no one else can get it. You need to provide this code to the new domain registrar, or else they will not be able to start the domain name transfer procedure. The EPP authentication codes are case-sensitive and may comprise of digits or special characters such as dots or commas, which can be easily mistyped, so make sure you copy/paste the right code. As an additional safety measure, the transfer code for a domain name may be changed on a regular basis. Some domain registrars call this code a domain password, an Auth key or a domain secret as well.
