All generic top-level domain name extensions and some country-code ones support a security lock functionality whose function is to prevent unapproved transfers of existing domains. Lots of domain registry operators that oversee country-code top-level domain names that do not support this feature are in the process of introducing it for the sake of security and for the convenience of the domain name owners. A domain name can be transferred only on the condition that it is unlocked and only an individual who has access to the account with the current domain registrar can accomplish that. New domain names are registered with the lock option activated deliberately, so as to impede any unsanctioned transfer attempts. The lock feature is among the security measures for controlling the transfer of existing domains between domain name registrars that have been introduced over the years.
