If you would like to transfer a domain from one registrar company to another, you’ll need to pass through several security steps. One of them is obtaining a unique EPP authorization code from the present domain name registrar – provided that you are the domain registrant, since the code is emailed to the domain owner’s email account and no one else can obtain it. You have to provide this code to the new domain registrar, or else they won’t be able to begin the transfer procedure. The EPP codes are case-sensitive and may comprise of digits or special characters such as dots or commas, which can be easily miswritten, so make sure you copy and paste the right code. As an additional security measure, the transfer code for a domain may be changed on a regular basis. Certain registrar companies refer to this code as an Auth key, a domain secret or a domain password as well.
