All generic extensions and certain country-code ones support a security lock option whose function is to stop unauthorized transfers of existing domain names. Lots of domain name registry operators that supervise country-code top-level domain names that do not support this option are in the process of adopting it for better safety and for the convenience of the domain name owners. A domain name can be transferred only if it is unlocked and only an individual who has been granted access to the account with the current registrar company can achieve that. New domains are registered with the lock option activated deliberately, so as to prevent any unsolicited transfer attempts. The lock option is among the safety measures for controlling the transfer of existing domains between domain registrars that have been introduced over the years.
