Transferring a domain name from one company to another traditionally involves the use of a unique transfer authorization code, which different companies call an EPP authorization code, a domain name password or an AuthInfo code. This code can be used as a protection measure against unapproved transfer attempts with all gTLD and with most ccTLD extensions. The code can be obtained only by the owner of the specific domain and is issued by the current registrar company. It must be given to the new registrar company because the transfer cannot be initiated without it. The code is case-sensitive and ordinarily includes digits and special characters, so as to impede unauthenticated persons from hijacking it. Some registrars even reset the codes of domain names registered through them from time to time for even better safety.
