Transferring a domain from one company to another ordinarily entails the use of a special transfer code, which different companies refer to as an EPP key, a domain password or an Auth code. This code can be used as a security mechanism against unauthorized transfer attempts with all generic and with most country-code extensions. It can be obtained only by the domain owner and is issued by the present domain registrar company. 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 digits and special characters, so as to stop unauthenticated individuals from guessing it. Certain companies even reset the codes of domain names registered through them from time to time for even greater safety.
