If you want to transfer a domain name from one company to another, you will need a special code, which may be called by multiple names – an EPP authentication code, an AuthInfo code, a domain name password, etc. All these names denote the exact same thing – a code that the domain name registrant obtains from the present domain name registrar and gives to the new one at the time of the order. Without a valid code, a domain transfer procedure cannot be initiated and this is one of the security measures against unsanctioned transfer attempts used with all gTLD and with most ccTLD extensions. For greater safety, the code comprises of numbers and/or special characters and is case-sensitive, so if you’d like to transfer one of your domains, you have to provide the new registrar company with the right code.
