All generic domain extensions and several country-code ones support a security lock feature whose function is to block unwanted transfers of active domains. Many registry operators that supervise country-code top-level domain names that do not support this feature are in the process of introducing it for better safety and for the convenience of the domain name registrants. A domain can be transferred only if it is unlocked and only a registrant who has access to the account with the current registrar can accomplish that. New domain names are registered with the lock option activated on purpose, so as to impede any unwanted transfer attempts. The lock feature is among the security measures for controlling the transfer of existing domain names between domain name registrars that have been introduced over the years.
