If you would like to transfer a domain from one domain registrar to another, you will need to go through several safety steps. One of them is getting a unique EPP authorization code from the current domain registrar – on the condition that you are the domain registrant, since the code is emailed to the domain owner’s email address and nobody else can obtain it. You have to provide this code to the new registrar company, otherwise they won’t be able to initiate the domain transfer. The EPP authentication codes are case-sensitive and may include digits or special symbols such as commas or dots, which can be easily mistyped, so make sure you copy and paste the correct code. As an extra safety measure, the transfer code for a domain may be altered regularly. Some registrar companies refer to this code as a domain password, a domain secret or an Auth key as well.
