If you decide to transfer a domain from one registrar company to another, you will have to go through several safety steps. One of them is obtaining a unique EPP code from the current registrar – as long as you are the registrant, since the code is sent to the owner's email address and no one else can obtain it. You have to provide this code to the new domain registrar, otherwise they won’t be able to begin the domain transfer process. The EPP authorization codes are case-sensitive and may include 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 additional protection measure, the transfer authorization code for a domain name may be reset on a regular basis. Certain domain registrars call this code a domain secret, an Auth key or a domain password as well.
