In case you wish to transfer a domain from one registrar company to another, you’ll need a special transfer code, which may be called by multiple names – an EPP authorization code, an AuthInfo code, a domain name password, and so on. All these names denote the same thing – a code that the domain registrant receives from the current domain name registrar and provides to the new one during the order process. Without an authentic code, a domain transfer procedure cannot be started and this is one of the security measures against unauthorized transfers used with all gTLD and with most ccTLD extensions. For better safety, the code contains digits and/or special symbols and is case-sensitive, so if you’d like to transfer one of your domains, you have to present the new company with the right code.
