If you wish to transfer a domain name from one registrar to another, you will have to pass through a couple of security steps. One of them is obtaining a special EPP authentication code from the present registrar company – as long as you are the registrant, since the code is emailed to the domain owner’s email address and no one else can get it. You need to give this code to the new registrar, or else they won’t be able to start the domain name transfer process. The EPP authentication codes are case-sensitive and may comprise of numbers or special symbols such as commas or dots, which can be easily miswritten, so make sure you copy/paste the right code. As an additional protection measure, the transfer code for a domain may be reset on a regular basis. Certain companies call this code a domain secret, an Auth key or a domain password as well.
