Transferring a domain name from one registrar company to another typically involves the use of a special transfer code, which different companies call an EPP key, a domain name password or an Auth code. This code can be used as a protection measure against unauthorized transfer attempts 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 registrar company. It must be given to the new registrar company because the transfer procedure cannot be initiated without it. The code is case-sensitive and traditionally comprises of digits and special characters, so as to stop unauthenticated people from guessing it. Certain registrar companies even reset the codes of domains registered through them after a given period of time for greater safety.
