All generic domain name extensions and some country-code ones support a security lock option whose purpose is to block unauthorized transfers of active domains. Lots of domain name registry organizations that supervise country-code TLDs that do not support this option are in the process of introducing it for better safety and for the convenience of the domain owners. A domain can be transferred only if it is unlocked and only a person who has been given access to the account with the current domain registrar can do that. New domain names are registered with the lock feature activated intentionally, so as to impede any unauthorized transfer attempts. The lock option is one of the security measures for controlling the transfer of existing domains between registrars that have been introduced over the years.
