All generic TLD extensions and several country-code ones support a security lock feature whose function is to hinder unauthorized transfers of existing domain names. Lots of domain name registry operators that supervise 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 owners. A domain name can be transferred only on the condition that it is unlocked and only a registrant who has been given access to the account with the current domain name registrar can do that. New domains are registered with the lock option activated on purpose, so as to block any unapproved transfer attempts. The lock option is one of the safety measures for regulating the transfer of existing domains between registrar companies that have been introduced over the years.
