Transferring a domain from one company to another commonly entails the use of a special transfer authorization code, which different companies refer to as an EPP authorization code, a domain name password or an Auth-Info code. This code can be used as a protection measure against unwanted transfer attempts with all generic and with most country-code extensions. The code can be obtained only by the owner of the specific domain and is provided by the present domain name registrar company. It must be given to the new registrar company because the transfer procedure cannot be started without it. The code is case-sensitive and commonly includes digits and special characters, so as to prevent unauthorized persons from hijacking it. Some domain name registrars even reset the codes of domain names registered through them after a certain period of time for even better security.
