All generic domain extensions and some country-code ones support a security lock functionality whose purpose is to stop unapproved transfers of existing domain names. Lots of domain name registry operators that manage country-code TLDs that do not support this option are in the process of introducing it for the sake of security and for the convenience of the domain owners. A domain name can be transferred only if it is unlocked and only a registrant who has been granted access to the account with the current registrar can achieve that. New domains are registered with the lock option activated on purpose, so as to impede any unwanted 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.
