If you wish to transfer a domain name from one domain name registrar to another, you will need to pass through a couple of security procedures. One of them is obtaining a unique EPP code from the present domain registrar – provided that you are the domain registrant, since the code is sent to the owner's email and no one else can get it. You will have to provide this code to the new domain registrar, otherwise they will not be able to initiate the domain transfer. The EPP codes are case-sensitive and may contain numbers or special symbols such as dots or commas, which can be easily miswritten, so make sure you copy and paste the correct code. As an extra protection measure, the transfer code for a domain name may be reset regularly. Certain domain registrars refer to this code as a domain password, an Auth key or a domain secret as well.
