All generic extensions and several country-code ones support a security lock option whose purpose is to hinder unsanctioned transfers of active domains. Many registry operators that oversee country-code Top-Level Domains that do not support this option are in the process of adopting it for the sake of security and for the convenience of the domain name registrants. A domain name can be transferred only on the condition that it is unlocked and only a person who has been given access to the account with the current registrar can do that. New domains are registered with the lock option enabled intentionally, so as to block any unauthorized transfer attempts. The lock option is one of the safety measures for controlling the transfer of active domains between domain name registrars that have been introduced over the years.
