In case you want to transfer a domain from one domain name registrar to another, you’ll need a unique authorization code, which may be referred to by different names – an EPP authentication code, an AuthInfo code, a domain name password, etc. All these names refer to the exact same thing – a code that the domain owner obtains from the present domain name registrar and provides to the new one at the time of the order. Without a valid code, a transfer cannot be initiated and this is one of the safety measures against unauthorized transfers used with all gTLD and with most ccTLD extensions. For better security, the code includes digits and/or special symbols and is case-sensitive, so if you wish to transfer one of your domains, you have to supply the new registrar with the correct code.
