Transferring a domain name from one company to another traditionally entails the use of a special transfer authorization code, which different companies call an EPP authorization code, a domain name password or an AuthInfo code. This code can be used as a protection mechanism against unapproved transfers with all generic and with most country-code extensions. The code can be obtained only by the owner of the given domain and is provided by the present domain registrar company. It must be given to the new registrar company because the transfer process cannot be initiated without it. The code is case-sensitive and frequently comprises of digits and special symbols, so as to hinder unauthorized persons from breaking it. Some companies even change the codes of domains registered through them every now and then for greater safety.
