If you decide to transfer a domain name from one domain name registrar to another, you’ll need to go through several security steps. One of them is getting a special EPP authentication code from the present domain name registrar – provided that you are the domain registrant, since the code is emailed to the owner's mailbox and no one else can get it. You’ll have to give this code to the new domain registrar, otherwise they won’t be able to begin the transfer. The EPP codes are case-sensitive and may comprise of digits or special symbols such as commas or dots, which can be easily miswritten, so make sure you copy & paste the right code. As an extra protection measure, the transfer authorization code for a domain name may be reset on a regular basis. Some domain name registrars call this code a domain password, an Auth key or a domain secret as well.
