If you would like to transfer a domain from one registrar to another, you will have to pass through a few safety steps. One of them is getting a unique EPP authentication code from the current registrar – as long as you are the domain registrant, since the code is sent to the owner's email and no one else can see it. You’ll need to give this code to the new domain name registrar, otherwise they will not be able to initiate the domain name transfer. The EPP authentication codes are case-sensitive and may comprise of digits or special symbols such as dots or commas, which can be easily miswritten, so make sure you copy/paste the correct code. As an additional security measure, the transfer code for a domain name may be changed on a regular basis. Some companies call this code a domain secret, a domain password or an Auth key as well.
