If you decide to transfer a domain name from one registrar company to another, you will have to go through a few safety steps. One of them is obtaining a special EPP authorization code from the present registrar – as long as you are the domain registrant, since the code is sent to the domain owner’s email and nobody else can get it. You have to provide this code to the new domain registrar, or else they won’t be able to begin the domain name transfer process. The EPP authentication codes are case-sensitive and may contain numbers or special symbols such as commas or dots, which can be easily mistyped, so make sure you copy & paste the right code. As an extra security measure, the transfer authorization code for a domain may be reset on a regular basis. Some registrars refer to this code as a domain secret, a domain password or an Auth key as well.
