All generic top-level domain name extensions and some country-code ones support a security lock feature whose purpose is to prevent unsanctioned transfers of existing domains. Many domain name registry organizations that manage country-code top-level domain names that do not support this feature are in the process of introducing it for the sake of security and for the convenience of the domain name registrants. A domain name can be transferred only if it is unlocked and only a registrant who has been granted access to the account with the current registrar can achieve that. New domains are registered with the lock feature enabled intentionally, so as to impede any unsolicited transfer attempts. The lock option is one of the security measures for controlling the transfer of active domains between domain name registrars that have been introduced over the years.
