Transferring a domain from one registrar company to another traditionally entails the use of a special domain name authorization code, which different companies refer to as an EPP authorization code, a domain name password or an Auth code. This code can be used as a safety mechanism against unapproved transfers with all generic and with most country-code extensions. It can be obtained only by the owner of the particular domain and is provided by the current registrar. It must be given to the new domain registrar company because the transfer process cannot be started without it. The code is case-sensitive and frequently includes digits and special characters, so as to obstruct unauthenticated individuals from guessing it. Certain registrars even alter the codes of domains registered through them after a certain amount of time for better safety.
