All generic top-level domain name extensions and some country-code ones support a security lock option whose function is to block unsanctioned transfers of active domains
. Many registry operators that manage country-code top-level domain names that do not support this feature are in the process of introducing it for greater security and for the convenience of the domain owners. A domain name 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 accomplish that. New domain names are registered with the lock feature enabled on purpose, so as to block any unapproved transfer attempts. The lock option is among the safety measures for regulating the transfer of existing domains between registrars that have been adopted over the years.
