All generic TLD extensions and certain country-code ones support a security lock option whose purpose is to block unsanctioned transfers of active domains. Lots of domain registry operators that supervise country-code top-level domain names that do not support this option are in the process of introducing it for better safety and for the convenience of the domain 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 domain registrar can achieve that. New domain names are registered with the lock feature enabled deliberately, so as to impede any unauthorized transfer attempts. The lock feature is among the security measures for regulating the transfer of existing domain names between registrars that have been adopted over the years.
