Transferring a domain from one company to another ordinarily entails the use of a special authorization code, which different registrar companies call 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 owner of the specific domain and is issued by the present domain registrar company. It must be given to the new registrar company because the transfer process cannot be initiated without it. The code is case-sensitive and commonly contains numbers and special characters, so as to obstruct unauthorized people from deciphering it. Certain domain name registrars even reset the codes of domain names registered through them after a particular period of time for even better safety.
