Transferring a domain from one registrar company to another normally entails the use of a special domain authorization code, which different registrar companies call an EPP authentication code, a domain password or an Auth-Info code. This code can be used as a safety mechanism against unsolicited transfers with all generic and with most country-code extensions. It can be obtained only by the domain owner and is provided by the current domain name 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 generally includes numbers and special characters, so as to hinder unauthorized persons from breaking it. Certain registrars even reset the codes of domains registered through them once in a while for even better safety.
