Transferring a domain name from one registrar company to another normally involves the use of a unique authorization 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 measure against unwanted transfers with all generic and with most country-code extensions. The code can be obtained only by the owner of the particular domain and is issued 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 ordinarily includes numbers and special characters, so as to prevent unauthenticated individuals from breaking it. Certain registrars even reset the codes of domain names registered through them every now and then for greater safety.
