If you want to transfer a domain name from one domain name registrar to another, you will have to go through a couple of security procedures. One of them is getting a special EPP code from the present registrar company – as long as you are the domain registrant, since the code is emailed to the domain owner’s mailbox and nobody else can see it. You will have to give this code to the new domain name registrar, otherwise they won’t be able to begin the domain transfer. The EPP authorization codes are case-sensitive and may comprise of numbers or special symbols such as dots or commas, which can be easily miswritten, so make sure you copy & paste the correct code. As an extra safety measure, the transfer code for a domain name may be changed on a regular basis. Some domain name registrars call this code a domain password, an Auth key or a domain secret as well.
