If you wish to transfer a domain name from one registrar company to another, you’ll have to pass through several safety steps. One of them is obtaining a unique EPP authorization code from the current registrar – on the condition that you are the domain registrant, since the code is sent to the domain owner’s mailbox and nobody else can see it. You’ll have to provide this code to the new registrar company, otherwise they won’t be able to begin the domain name transfer. The EPP authorization codes are case-sensitive and may contain numbers or special characters such as commas or dots, which can be easily miswritten, so make sure you copy/paste the right code. As an extra protection measure, the transfer authorization code for a domain name may be altered on a regular basis. Certain domain registrars refer to this code as a domain password, a domain secret or an Auth key as well.
