Transferring a domain from one company to another typically involves the use of a unique domain name authorization code, which different companies refer to as an EPP authorization code, a domain name password or an Auth-Info code. This code can be used as a safety measure against unsolicited transfer attempts with all gTLD and with most ccTLD extensions. The code can be obtained only by the owner of the particular domain name and is provided by the present domain registrar company. It must be given to the new domain name registrar company because the transfer process cannot be initiated without it. The code is case-sensitive and commonly includes numbers and special symbols, so as to stop unauthorized people from cracking it. Certain companies even reset the codes of domains registered through them every once in a while for even better security.
