In case you want to transfer a domain from one domain registrar to another, you’ll need a unique code, which may be referred to by various names – an EPP key, an Auth code, a domain name password, etc. All these names refer to one and the same thing – a code that the domain owner gets from the current domain registrar and gives to the new one during the order procedure. Without a valid code, a domain transfer cannot be initiated and this is one of the protection measures against unsolicited transfer attempts used with all gTLD and with most ccTLD extensions. For better safety, the code contains digits and/or special characters and is case-sensitive, so if you would like to transfer one of your domains, you have to supply the new company with the right code.
