If you’d like to transfer a domain from one domain registrar to another, you’ll need to go through several safety procedures. One of them is getting a special EPP authentication code from the current registrar – as long as you are the registrant, since the code is emailed to the owner's email address and nobody else can see it. You will need to give this code to the new domain name registrar, otherwise they will not be able to initiate the domain name transfer procedure. The EPP authorization codes are case-sensitive and may comprise of digits or special characters such as dots or commas, which can be easily misentered, so make sure you copy & paste the right code. As an additional security measure, the transfer authorization code for a domain name may be changed on a regular basis. Some registrars call this code a domain secret, a domain password or an Auth key as well.
