Transferring a domain from one company to another generally entails the use of a special transfer code, which different companies call an EPP authorization code, a domain name password or an AuthInfo code. This code can be used as a safety mechanism against unsanctioned transfers with all generic and with most country-code extensions. It can be obtained only by the owner of the given domain and is issued by the current registrar company. It must be given to the new domain name registrar company because the transfer cannot be initiated without it. The code is case-sensitive and generally comprises of digits and special symbols, so as to hinder unauthenticated persons from breaking it. Some registrars even reset the codes of domains registered through them after a certain amount of time for even greater security.
