Transferring a domain name from one company to another ordinarily involves the use of a unique authorization code, which different companies refer to as an EPP authorization code, a domain password or an Auth code. This code can be used as a protection mechanism against unsanctioned transfer attempts with all generic and with most country-code extensions. It can be obtained only by the owner of the specific domain and is issued by the current registrar. 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 contains numbers and special characters, so as to stop unauthenticated people from guessing it. Some companies even alter the codes of domains registered through them from time to time for greater safety.
