All generic Top-Level Domain extensions and some country-code ones support a security lock feature whose function is to impede unsanctioned transfers of existing domains. Lots of domain name registry operators that supervise country-code top-level domain names that don’t support this option are in the process of adopting it for greater safety and for the convenience of the domain registrants. A domain name can be transferred only on the condition that it is unlocked and only a registrant who has access to the account with the current domain registrar can achieve that. New domains are registered with the lock option activated deliberately, so as to prevent any unauthorized transfer attempts. The lock option is among the security measures for controlling the transfer of existing domains between domain name registrars that have been adopted over the years.
