All generic domain extensions and certain country-code ones support a security lock option whose function is to block unauthorized transfers of existing domain names. Lots of registry operators that oversee ccTLDs that don’t support this option are in the process of introducing it for greater security and for the convenience of the domain 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 company can do that. New domains are registered with the lock option enabled deliberately, so as to hinder any unsolicited transfer attempts. The lock feature is among the security measures for controlling the transfer of existing domain names between registrar companies that have been introduced over the years.
