All generic extensions and several country-code ones support a security lock option whose purpose is to prevent unauthorized transfers of active domains. Lots of domain name registry operators that supervise 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 registrants. A domain can be transferred only if it is unlocked and only a person who has been given access to the account with the current registrar can achieve that. New domains are registered with the lock option activated on purpose, so as to stop any unsolicited transfer attempts. The lock feature is one of the safety measures for controlling the transfer of active domains between registrars that have been introduced over the years.
