Transferring a domain from one company to another generally involves the use of a special domain authorization code, which different registrar companies refer to as an EPP key, a domain password or an AuthInfo code. This code can be used as a protection mechanism against unsolicited transfer attempts with all generic and with most country-code extensions. The code can be obtained only by the domain owner and is provided by the present domain registrar company. It must be given to the new domain registrar company because the transfer procedure cannot be initiated without it. The code is case-sensitive and ordinarily includes numbers and special characters, so as to obstruct unauthenticated individuals from guessing it. Certain companies even reset the codes of domain names registered through them after a given interval of time for better safety.
