Transferring a domain from one company to another typically involves the use of a unique domain name authorization code, which different registrar companies call an EPP authentication code, a domain name password or an Auth-Info code. This code can be used as a safety measure against unauthorized transfer attempts with all generic and with most country-code extensions. The code can be obtained only by the domain name owner and is provided by the current domain name registrar company. It must be given to the new registrar because the transfer process cannot be started without it. The code is case-sensitive and usually contains numbers and special characters, so as to hinder unauthorized persons from deciphering it. Certain registrars even alter the codes of domain names registered through them every now and then for even better safety.
