If you would like to transfer a domain name from one company to another, you will need to go through a couple of security steps. One of them is obtaining a special EPP authentication code from the current domain registrar – provided that you are the domain registrant, since the code is emailed to the owner's mailbox and nobody else can get it. You will need to provide this code to the new registrar company, otherwise they will not be able to initiate the domain name transfer procedure. 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 & paste the right code. As an additional safety measure, the transfer code for a domain name may be reset regularly. Some companies refer to this code as a domain secret, a domain password or an Auth key as well.
