Transferring a domain name from one registrar company to another normally entails the use of a unique transfer authorization code, which different registrar companies call an EPP key, a domain password or an Auth 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 current domain name registrar company. It must be given to the new registrar because the transfer procedure cannot be started without it. The code is case-sensitive and traditionally includes digits and special symbols, so as to impede unauthorized individuals from breaking it. Certain registrars even alter the codes of domain names registered through them after a given amount of time for greater safety.
