If you wish to transfer a domain from one registrar to another, you’ll need a special domain name authorization code, which may be referred to by various names – an EPP key, an AuthInfo code, a domain password, etc. All these names refer to the exact same thing – a code that the domain name registrant gets from the current domain name registrar and gives to the new one at the time of the order. Without a genuine code, a domain transfer cannot be started and this is one of the protection measures against unapproved transfers used with all gTLD and with most ccTLD extensions. For even greater 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 need to supply the new domain name registrar with the right code.
