Transferring a domain name from one registrar company to another typically entails the use of a unique transfer authorization code, which different registrar companies call an EPP authorization code, a domain password or an AuthInfo code. This code can be used as a protection measure against unwanted transfer attempts with all generic and with most country-code extensions. The code can be obtained only by the owner of the specific domain name and is provided by the current registrar. It must be given to the new registrar company because the transfer process cannot be started without it. The code is case-sensitive and generally comprises of digits and special characters, so as to prevent unauthorized individuals from guessing it. Some companies even alter the codes of domain names registered through them after a particular period of time for even greater security.
