Transferring a domain from one company to another typically involves the use of a special authorization code, which different companies refer to as an EPP authorization code, a domain password or an Auth-Info code. This code can be used as a safety mechanism against unwanted transfer attempts with all gTLD and with most ccTLD extensions. The code can be obtained only by the domain name owner and is issued by the current domain registrar company. It must be given to the new registrar company because the transfer process cannot be started without it. The code is case-sensitive and normally comprises of numbers and special symbols, so as to prevent unauthenticated persons from guessing it. Some registrars even reset the codes of domains registered through them once in a while for greater safety.
