All generic TLD extensions and several country-code ones support a security lock option whose function is to prevent unsolicited transfers of existing domains. Lots of domain registry operators that supervise country-code TLDs that do not support this feature are in the process of adopting it for the sake of security and for the convenience of the domain name owners. A domain can be transferred only on the condition that it is unlocked and only a registrant who has access to the account with the current domain name registrar can accomplish that. New domain names are registered with the lock feature activated deliberately, so as to prevent any unapproved transfer attempts. The lock feature is among the safety measures for controlling the transfer of existing domains between domain name registrars that have been adopted over the years.
