Emergency screen privacy
How can I protect privacy when I cannot reach the keyboard or mouse?
Short answer
You need a trigger that was enabled and tested in advance, such as removing a USB device, moving a Bluetooth device out of range, or using a camera gesture. Without prior setup, software cannot infer your intent in the moment.
Prepare remote triggers before you need them
USB removal works when you can take the device with you. Bluetooth suits leaving with a wearable or phone. A camera gesture can help while you remain visible but cannot touch the PC.
Automatic triggers depend on connection quality, distance, visibility, and the environment. Try the setup several times in a safe situation and retain a manual shortcut as a fallback.
- Avoid enabling many untested triggers at once
- Start with reversible actions such as hiding or locking
- Keep restart and shutdown actions disabled unless truly needed
