If you’d like to transfer a domain from one registrar company to another, you will need a unique transfer code, which may be called by multiple names – an EPP authentication code, an Auth-Info code, a domain password, and so on. All these names refer to the exact same thing – a code that the domain registrant receives from the present registrar and provides to the new one at the time of the order. Without a valid code, a transfer procedure cannot be initiated and this is one of the security measures against unsolicited transfer attempts used with all generic and with most country-code extensions. For even greater security, the code includes digits and/or special symbols and is case-sensitive, so if you wish to transfer one of your domain names, you need to supply the new domain name registrar with the correct code.
