All generic Top-Level Domain extensions and certain country-code ones support a security lock option whose function is to prevent unapproved transfers of existing domain names. Lots of domain registry operators that oversee ccTLDs that don’t support this feature are in the process of introducing it for better security and for the convenience of the domain name registrants. A domain can be transferred only on the condition that it is unlocked and only a registrant who has access to the account with the current registrar can do that. New domains are registered with the lock option activated on purpose, so as to stop any unwanted transfer attempts. The lock option is among the security measures for controlling the transfer of active domains between registrars that have been adopted over the years.
