Transferring a domain from one company to another traditionally involves the use of a special authorization code, which different companies call an EPP key, a domain name password or an Auth code. This code can be used as a safety mechanism against unwanted transfers with all generic and with most country-code extensions. It can be obtained only by the domain registrant and is provided by the current domain name registrar company. It must be given to the new domain name registrar company because the transfer procedure cannot be initiated without it. The code is case-sensitive and frequently contains digits and special characters, so as to impede unauthorized individuals from hijacking it. Certain registrar companies even reset the codes of domain names registered through them every now and then for even better security.
