Transferring a domain name from one company to another generally entails the use of a unique domain name authorization code, which different companies call an EPP key, a domain password or an AuthInfo code. This code can be used as a safety measure against unsanctioned transfers with all generic and with most country-code 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 procedure cannot be started without it. The code is case-sensitive and typically contains digits and special characters, so as to hinder unauthorized people from guessing it. Certain domain name registrars even reset the codes of domains registered through them every once in a while for greater security.
