All generic extensions and several country-code ones support a security lock feature whose purpose is to hinder unapproved transfers of existing domains. Lots of domain name registry operators that oversee country-code TLDs that don’t support this option are in the process of adopting it for the sake of safety and for the convenience of the domain name owners. A domain can be transferred only if 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 domain names are registered with the lock option enabled on purpose, so as to impede any unapproved transfer attempts. The lock option is one of the security measures for controlling the transfer of existing domain names between domain name registrars that have been introduced over the years.
