password hash problem

Hello, I need to create many users in wordpress with this plugin. I created an csv with my user information. Then i import to wordpress. Everything works fine except the password. In my csv, i input the password 123456 for example. But i cannot login with this password. Do i need to enter a hash password in my csv before import? or is there any options that can make the user password exact match with the password that i input in my csv? Thanks.
