All generic domain name extensions and certain country-code ones support a security lock feature whose function is to block unapproved transfers of existing domain names. Lots of registry operators that oversee country-code top-level domain names that don’t support this feature are in the process of adopting it for better safety and for the convenience of the domain name registrants. A domain can be transferred only if it is unlocked and only a person who has been granted access to the account with the current registrar can do that. New domain names are registered with the lock option enabled deliberately, so as to stop any unauthorized transfer attempts. The lock option is among the safety measures for controlling the transfer of existing domain names between registrars that have been introduced over the years.
