All generic top-level domain name extensions and certain country-code ones support a security lock option whose function is to block unauthorized transfers of active domain names. Lots of domain name registry operators that oversee country-code TLDs that do not support this feature are in the process of adopting it for the sake of security and for the convenience of the domain registrants. A domain can be transferred only on the condition that it is unlocked and only an individual who has been granted access to the account with the current registrar company can do that. New domains are registered with the lock option activated on purpose, so as to prevent any unwanted transfer attempts. The lock option is one of the security measures for controlling the transfer of existing domains between domain registrars that have been introduced over the years.
