Transferring a domain name from one company to another generally entails the use of a special domain name authorization code, which different companies refer to as an EPP key, a domain password or an AuthInfo code. This code can be used as a safety mechanism against unapproved transfer attempts with all generic and with most country-code extensions. The code can be obtained only by the owner of the given domain and is provided by the present registrar. It must be given to the new registrar because the transfer procedure cannot be started without it. The code is case-sensitive and typically contains digits and special symbols, so as to stop unauthenticated people from guessing it. Some domain registrars even change the codes of domains registered through them after a particular period of time for even greater safety.
