If you’d like to transfer a domain name from one registrar company to another, you will need to go through several security procedures. One of them is getting a unique EPP authentication code from the present domain registrar – provided that you are the domain registrant, since the code is emailed to the domain owner’s email address and nobody else can get it. You’ll need to provide this code to the new domain registrar, otherwise they won’t be able to begin the transfer process. The EPP authorization codes are case-sensitive and may contain numbers 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 reset on a regular basis. Some domain name registrars call this code a domain secret, an Auth key or a domain password as well.
