If you decide to transfer a domain name from one domain registrar to another, you will have to go through a few security procedures. One of them is obtaining a unique EPP authorization code from the present domain registrar – provided that you are the registrant, since the code is emailed to the domain owner’s mailbox and no one else can see it. You have to provide this code to the new registrar company, otherwise they will not be able to initiate the transfer procedure. The EPP authorization codes are case-sensitive and may comprise of numbers or special symbols such as commas or dots, which can be easily mistyped, so make sure you copy and paste the correct code. As an extra security measure, the transfer authorization code for a domain may be reset on a regular basis. Certain domain name registrars call this code a domain secret, an Auth key or a domain password as well.
