In case you’d like to transfer a domain from one registrar to another, you’ll need a unique authorization code, which may be referred to by multiple names – an EPP key, an AuthInfo code, a domain name password, etc. All these names designate the very same thing – a code that the domain name owner gets from the present registrar and gives to the new one upon ordering. Without a genuine code, a domain name transfer procedure cannot be started and this is one of the security measures against unsanctioned transfer attempts used with all gTLD and with most ccTLD extensions. For even better security, the code contains numbers and/or special characters and is case-sensitive, so in case you’d like to transfer one of your domain names, you have to supply the new registrar with the correct code.
