Transferring a domain name from one registrar company to another traditionally entails the use of a unique domain name authorization code, which different companies refer to as an EPP authentication code, a domain password or an Auth code. This code can be used as a protection measure against unsanctioned transfer attempts 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 registrar. It must be given to the new registrar company because the transfer cannot be started without it. The code is case-sensitive and traditionally contains digits and special characters, so as to stop unauthenticated individuals from guessing it. Certain registrar companies even reset the codes of domain names registered through them after a given interval of time for even better safety.
