Transferring a domain from one company to another traditionally 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 code. This code can be used as a security mechanism against unsanctioned 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 registrar company. It must be given to the new registrar company because the transfer process cannot be started without it. The code is case-sensitive and usually comprises of digits and special symbols, so as to stop unauthenticated people from cracking it. Some registrar companies even reset the codes of domains registered through them after a given period of time for better security.
