    else
      print("12. error: ", err)
    end
    
    -- You don't need to supply old pass as nil, so the above is same as:
    local ok, err = password.check('newpass', { min = "disabled,24,11,9,8", match = 3 })
    if ok then
      print("13. success: ", "new password is fine")
    else
      print("13. error: ", err)
    end
    
    -- If you need to run more tests with same settings, you can use:
    local quality = password.new({ min = "disabled,24,11,9,8", match = 3 })
    local ok, err = quality:check("This!Is2Awesom3!", "IUsedToUse7his")
    if ok then
      print("14. success: ", "new password is fine")
    else
      print("14. error: ", err)
    end
