All generic domain extensions and several country-code ones support a security lock option whose function is to prevent unauthorized transfers of existing domains. Many domain registry operators that supervise country-code Top-Level Domains that don’t support this feature are in the process of introducing it for better security and for the convenience of the domain owners. A domain can be transferred only on the condition that it is unlocked and only a registrant who has access to the account with the current domain name registrar can achieve that. New domain names are registered with the lock feature activated deliberately, so as to hinder any unsanctioned transfer attempts. The lock option is one of the security measures for regulating the transfer of existing domain names between registrars that have been adopted over the years.
