Transferring a domain name from one company to another normally entails the use of a unique transfer code, which different registrar companies call an EPP key, a domain password or an Auth-Info code. This code can be used as a security mechanism against unsolicited transfer attempts with all gTLD and with most ccTLD extensions. The code can be obtained only by the owner of the particular domain name and is provided by the current domain registrar company. It must be given to the new domain registrar company because the transfer procedure cannot be initiated without it. The code is case-sensitive and generally comprises of numbers and special symbols, so as to obstruct unauthorized people from cracking it. Certain registrars even reset the codes of domains registered through them every once in a while for even better safety.
