You can add a “digital lock” to the device, which will require entering a passcode to access the Hero dispenser menus. Only scheduled dose dispense will be available on the dispenser without any passcode entry.
This setting is available via the app under More > Notifications & Preferences > Caregiver & Member preferences:
Under Access to Hero device menus, tap the on/off switch and an overlay will appear
Tap the arrows to create a 4 digit code then tap the Add button to create the menu passcode
Tap the Update button to confirm any changes
