All generic domain extensions and several country-code ones support a security lock option whose purpose is to block unapproved transfers of existing domain names. Many domain registry organizations that supervise country-code TLDs that do not support this option are in the process of introducing it for the sake of safety and for the convenience of the domain name registrants. A domain can be transferred only on the condition that it is unlocked and only a person who has been granted access to the account with the current domain registrar can do that. New domain names are registered with the lock option activated deliberately, so as to prevent any unauthorized transfer attempts. The lock feature is among the safety measures for controlling the transfer of existing domains between domain name registrars that have been adopted over the years.
