All generic extensions and some country-code ones support a security lock option whose function is to stop unwanted transfers of existing domains. Lots of domain name registry operators that manage country-code TLDs that do not support this option are in the process of introducing it for better security and for the convenience of the domain owners. A domain name can be transferred only if it is unlocked and only a registrant who has been given access to the account with the current registrar can achieve that. New domains are registered with the lock option enabled intentionally, so as to impede any unsanctioned transfer attempts. The lock option is among the safety measures for regulating the transfer of existing domain names between domain name registrars that have been introduced over the years.
