Transferring a domain from one company to another ordinarily involves the use of a special domain name authorization code, which different companies call an EPP authentication code, a domain password or an Auth-Info code. This code can be used as a protection measure against unsanctioned transfers with all gTLD and with most ccTLD extensions. The code can be obtained only by the owner of the specific domain and is provided by the current domain name registrar company. It must be given to the new domain registrar company because the transfer procedure cannot be started without it. The code is case-sensitive and ordinarily includes numbers and special symbols, so as to stop unauthorized individuals from cracking it. Some domain name registrars even reset the codes of domains registered through them after a particular period of time for even better safety.
