If you’d like to transfer a domain name from one registrar to another, you’ll have to go through a couple of security procedures. One of them is obtaining a unique EPP authorization code from the current domain name registrar – on the condition that you are the registrant, since the code is emailed to the domain owner’s email account and no one else can see it. You will need to provide this code to the new registrar company, or else they won’t be able to start the domain name transfer process. The EPP authorization codes are case-sensitive and may comprise of digits or special characters such as commas or dots, which can be easily miswritten, so make sure you copy/paste the correct code. As an extra security measure, the transfer authorization code for a domain may be changed regularly. Certain companies refer to this code as a domain password, a domain secret or an Auth key as well.
