Settings Authentication Session
The settings page is locked using the device's Biometrics or Credentials (if set).
Once unlocked, it will not prompt for login for the next 5 minutes. This persisting session duration reset each time a settings page is accessed.
When the device is locked, or the app is exited or placed in the background, the authentication session will be revoked.

App Pinning
For better security, go to the App Pinning setting, tap into it to view more options, then enable Ask for PIN/pattern/password before unpinning.
On some devices, it may be shown as Lock device when unpinning or equivalent.
This will ensure that users cannot unpin (and thus unlock) the kiosk view without first entering your device biometrics or credentials.
