Transferring a domain name from one company to another traditionally involves the use of a special transfer code, which different companies refer to as an EPP key, a domain name password or an AuthInfo code. This code can be used as a safety mechanism against unauthorized transfer attempts with all generic and with most country-code extensions. It can be obtained only by the owner of the particular domain name and is issued by the present registrar. It must be given to the new domain registrar company because the transfer process cannot be started without it. The code is case-sensitive and normally includes numbers and special symbols, so as to stop unauthenticated persons from deciphering it. Some registrars even reset the codes of domains registered through them from time to time for better safety.
