All generic top-level domain name extensions and certain country-code ones support a security lock option whose function is to stop unwanted transfers of existing domains. Lots of domain name registry operators that oversee 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 registrants. A domain can be transferred only on the condition that it is unlocked and only a registrant who has been given access to the account with the current domain name registrar can accomplish that. New domains are registered with the lock feature enabled intentionally, so as to block any unauthorized transfer attempts. The lock option is one of the safety measures for regulating the transfer of existing domains between registrar companies that have been adopted over the years.
