All generic domain name extensions and some country-code ones support a security lock option whose purpose is to hinder unauthorized transfers of existing domains. Many registry organizations that oversee country-code top-level domain names that do not support this option are in the process of adopting it for better safety and for the convenience of the domain owners. A domain 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 domain names are registered with the lock feature activated deliberately, so as to prevent any unapproved transfer attempts. The lock option is one of the security measures for regulating the transfer of active domains between domain registrars that have been adopted over the years.
