This FAQ item will help you enable Kiosk Mode on your iPad. The steps below are for iPadOS 13 and later, where Accessibility has its own row in the main Settings list instead of sitting under General.
Keep the screen on
Go to Settings > Display & Brightness and set “Auto-Lock” to “Never”.

Enable Guided Access
Go to Settings > Accessibility, scroll down to the “General” section and tap “Guided Access”.

Turn it on and set a passcode under “Passcode Settings”.
On the same screen, open “Display Auto-Lock” and set it to “Never”. This is a list, not a switch: it runs from “Default”, through durations from 30 seconds to 15 minutes, to “Never”. “Default” means the iPad follows the “Auto-Lock” you just set in Display & Brightness, so anything other than “Never” still lets the screen lock while Guided Access is running. On iPadOS 12 and earlier this row was a switch called “Mirror Display Auto-Lock”.

Next, go back to Settings > Accessibility, scroll to the bottom and tap “Accessibility Shortcut”. Set it to “Guided Access”.

Now, boot up the Vizito app and triple-click the Home button to go to the Guided Access menu. If you use an iPad with no home button, you can activate Guided Access by triple-clicking the top button.

Tap “Session Settings” and switch off “Top Button”, “Volume Buttons” and “Motion”, so a visitor cannot put the iPad to sleep, change the volume or set anything off by shaking it. On iPadOS 12 and earlier these sat behind a “Hardware Buttons” button instead, and “Top Button” was called “Sleep/Wake Button”.

Tap “Start” and Guided Access takes over the screen. The button reads “Resume” instead when a session is already configured for that app.
Disable Guided Access
To stop Guided Access, triple-click the home button again and enter the passcode. Tap on Stop.
The screen never turns off and you want it to
Everything above is meant to keep the kiosk awake. If your problem is the opposite one, that the iPad refuses to sleep, check these three in this order:
- “Keep tablet awake” in Vizito. In the backoffice, “Account settings” > “General” > “Advanced settings” holds a “Keep tablet awake” switch. While it is on, the app itself holds the display on and no iPadOS setting will let the screen sleep. See Advanced settings.
- “Display Auto-Lock” in Guided Access, under Settings > Accessibility > Guided Access. Set it to “Default” or to a duration instead of “Never”.
- “Auto-Lock” in Settings > Display & Brightness. Set it to a duration instead of “Never”.
A tablet that has not been activated yet keeps its screen on whatever you set, because it has no account settings to read. The same goes for the screen showing the contactless sign-in QR code.
To save power without letting the tablet sleep, dim the screen outside your opening hours instead: see Energy saving.
