All generic domain name extensions and certain country-code ones support a security lock option whose function is to block unauthorized transfers of active domains. Lots of domain registry operators that oversee country-code TLDs that don’t support this option are in the process of adopting it for the sake of security and for the convenience of the domain name registrants. 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 registrar company can accomplish that. New domain names are registered with the lock feature enabled intentionally, so as to prevent any unwanted transfer attempts. The lock option is among the security measures for regulating the transfer of existing domain names between domain registrars that have been adopted over the years.
