How Can i create Users without password only username in batch process

I need to create many users without password only username Plz i need help
Ps. when i create batch users..

Hello!

I Usually Use This Way.
Step1)
Go to UserManager → Users → Add → Batch and Create Users by Batch

Step2)
Run This Script :

 :local from 1;:local to 10;:local i 0;
 :foreach id in=[/tool user-manager user find] do={:if ($i >= $from && $i <= $to) do={/tool user-manager user set password="" $id}; :set i ($i+1)}

1 is My First Username Index Number (Created by Batch Process) and 10 is My Last Username Index Number(Created by Batch Process)

You Can Use This Way and Set First & Last Index Number.

Nice Tip! but username must be then COMPLEX enough so that guessing should be impossible for guest. IMO username should be 10-12 characters long.
