Can an intruder deactivate the alarm with my tablet?

Hi folks, I’m just wrapping up a successful installation of my konnected pro panel. I am in the process of getting two tablets installed where we previously had keypads. I have installed the Fully Kiosk browser and I have my.smartthings.com running. Unless I put a passcode on my tablet, could an intruder not simply touch “disarm” and turn off the alarm? I have yet to perfect the automatic arming and disarming based on the fact that my kids often come home with a dead phone, so the tablet is necessary by the door. Is there a way to include a code for disarming?
