If you would like to transfer a domain from one domain name registrar to another, you’ll have to go through several security procedures. One of them is obtaining a unique EPP authentication code from the present registrar – as long as you are the domain registrant, since the code is emailed to the domain owner’s email account and no one else can see it. You’ll need to provide this code to the new registrar company, or else they won’t be able to begin the domain transfer. The EPP codes are case-sensitive and may comprise of 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 authorization code for a domain may be altered on a regular basis. Certain registrars call this code a domain password, a domain secret or an Auth key as well.
