All generic extensions and some country-code ones support a security lock option whose function is to impede unwanted transfers of active domain names. Many domain name registry operators that oversee country-code Top-Level Domains that do not support this option are in the process of adopting it for greater safety and for the convenience of the domain registrants. A domain can be transferred only if it is unlocked and only a registrant who has been given access to the account with the current domain name registrar can achieve that. New domains are registered with the lock feature enabled deliberately, so as to stop any unsolicited transfer attempts. The lock option is one of the safety measures for controlling the transfer of active domain names between domain registrars that have been adopted over the years.
