In case you want to transfer a domain from one registrar to another, you will need a unique transfer code, which may be referred to by different names – an EPP authentication code, an AuthInfo code, a domain password, and so on. All these names refer to the same thing – a code that the domain owner gets from the current domain name registrar and provides to the new one at the time of the order. Without a genuine code, a domain transfer cannot be initiated and this is one of the security mechanisms against unauthorized transfer attempts used with all generic and with most country-code extensions. For greater safety, the code contains numbers and/or special symbols and is case-sensitive, so if you want to transfer one of your domains, you have to provide the new registrar with the correct code.
