All generic domain name extensions and several country-code ones support a security lock functionality whose function is to block unapproved transfers of existing domain names. Many domain registry organizations that supervise country-code top-level domain names that don’t support this option are in the process of adopting it for better security and for the convenience of the domain registrants. A domain name can be transferred only if 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 feature enabled deliberately, so as to prevent any unsanctioned transfer attempts. The lock option is one of the security measures for controlling the transfer of existing domain names between registrars that have been introduced over the years.
