If you want to transfer a domain name from one registrar to another, you’ll have to pass through a few safety steps. One of them is getting a special EPP code from the current domain name registrar – as long as you are the domain registrant, since the code is emailed to the owner's email account and no one else can obtain it. You will need to provide this code to the new domain name registrar, or else they will not be able to begin the transfer. The EPP authentication codes are case-sensitive and may include numbers or special symbols such as dots or commas, which can be easily miswritten, so make sure you copy & paste the right code. As an additional safety measure, the transfer code for a domain may be altered on a regular basis. Some registrars refer to this code as an Auth key, a domain password or a domain secret as well.
