All generic extensions and certain country-code ones support a security lock option whose purpose is to stop unapproved transfers of active domain names. Many domain name registry operators that manage country-code top-level domain names that do not support this feature are in the process of introducing it for better 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 domain registrar can do that. New domains are registered with the lock option enabled deliberately, so as to block any unsolicited transfer attempts. The lock option is one of the safety measures for controlling the transfer of existing domains between domain name registrars that have been introduced over the years.
