If you would like to transfer a domain name from one registrar company to another, you will need to pass through a few security procedures. One of them is getting a special EPP authorization code from the current registrar – provided that you are the registrant, since the code is emailed to the owner's email address and no one else can see it. You need to give this code to the new registrar company, or else they won’t be able to start the domain transfer process. The EPP codes are case-sensitive and may comprise of numbers or special symbols such as commas or dots, which can be easily miswritten, so make sure you copy & paste the right code. As an additional protection measure, the transfer code for a domain may be reset regularly. Certain companies refer to this code as a domain password, an Auth key or a domain secret as well.
