In case you would like to transfer a domain from one company to another, you’ll need a special transfer authorization code, which may be called by multiple names – an EPP key, an Auth-Info code, a domain password, etc. All these names refer to the exact same thing – a code that the domain owner obtains from the present domain registrar and provides to the new one during the order process. 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 if you’d like to transfer one of your domain names, you have to provide the new domain registrar with the right code.
