Transferring a domain name from one company to another ordinarily involves the use of a unique transfer authorization code, which different registrar 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 transfers with all generic and with most country-code extensions. It can be obtained only by the owner of the particular domain and is issued by the current domain registrar company. It must be given to the new registrar because the transfer procedure cannot be initiated without it. The code is case-sensitive and frequently includes digits and special symbols, so as to prevent unauthenticated individuals from guessing it. Some registrars even reset the codes of domain names registered through them after a particular period of time for better safety.
