Transferring a domain name from one registrar company to another commonly involves the use of a special domain name authorization code, which different companies refer to as an EPP authentication code, a domain name password or an Auth-Info code. This code can be used as a security measure against unsolicited transfers with all generic and with most country-code extensions. The code can be obtained only by the owner of the particular domain name and is issued by the current domain registrar company. It must be given to the new registrar company because the transfer cannot be initiated without it. The code is case-sensitive and traditionally comprises of digits and special symbols, so as to hinder unauthorized persons from deciphering it. Certain domain registrars even reset the codes of domain names registered through them from time to time for even greater safety.
