Transferring a domain from one company to another ordinarily involves the use of a special transfer authorization code, which different registrar companies call an EPP authentication code, a domain name password or an AuthInfo code. This code can be used as a safety mechanism against unsolicited transfers with all generic and with most country-code extensions. It can be obtained only by the owner of the given domain name and is provided by the current domain name registrar company. It must be given to the new domain registrar company because the transfer process cannot be started without it. The code is case-sensitive and frequently contains digits and special symbols, so as to hinder unauthorized individuals from breaking it. Some domain name registrars even alter the codes of domains registered through them after a given interval of time for even better safety.
