Transferring a domain name from one company to another ordinarily entails the use of a special domain authorization code, which different registrar companies refer to as an EPP authorization code, a domain password or an AuthInfo code. This code can be used as a safety mechanism against unsanctioned transfer attempts with all gTLD and with most ccTLD extensions. The code can be obtained only by the domain name owner and is provided by the present registrar. It must be given to the new domain registrar company because the transfer cannot be initiated without it. The code is case-sensitive and traditionally contains numbers and special symbols, so as to hinder unauthorized individuals from hijacking it. Certain registrar companies even alter the codes of domains registered through them once in a while for even greater security.
