Transferring a domain name from one registrar company to another usually involves the use of a special transfer code, which different registrar companies refer to as an EPP authentication code, a domain name password or an Auth-Info code. This code can be used as a safety mechanism against unsanctioned transfers with all gTLD and with most ccTLD extensions. It can be obtained only by the owner of the given domain and is issued by the current registrar. It must be given to the new registrar because the transfer procedure cannot be started without it. The code is case-sensitive and typically includes numbers and special symbols, so as to stop unauthorized individuals from breaking it. Certain registrars even reset the codes of domain names registered through them once in a while for even better security.
