In case you wish to transfer a domain from one company to another, you will need a unique authorization code, which may be referred to by various names – an EPP authentication code, an AuthInfo code, a domain password, etc. All these names denote the exact same thing – a code that the domain registrant gets from the current registrar and gives to the new one during the order procedure. Without a genuine code, a domain name transfer cannot be initiated and this is one of the security mechanisms against unauthorized 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 wish to transfer one of your domain names, you need to supply the new domain registrar with the correct code.
