Use Lock Screen Password to Power Off OPPO Phone
Enabling a lock screen password on your OPPO device is essential to prevent unauthorized access to your device, particularly when it gets lost or stolen. The same goes when shutting off your device; verifying the lock screen password prevents it from intentionally powering off the device. For more information and how to enable it, please read on.
Note: Available for ColorOS 13 and above models only. Check your ColorOS version in [Settings] > [About Phone] / [About Device].
How to enable password to power off
Go to [Settings] > [Security and privacy] > [More security and privacy] > and toggle to on/off the [Require Password to power off].
