All generic extensions and some country-code ones support a security lock functionality whose function is to stop unsolicited transfers of existing domains. Many registry operators that supervise country-code TLDs that don’t support this feature are in the process of introducing it for the sake of security and for the convenience of the domain registrants. A domain name 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 do that. New domain names are registered with the lock feature activated deliberately, so as to prevent any unsolicited transfer attempts. The lock option is among the security measures for controlling the transfer of existing domains between registrars that have been adopted over the years.
