What it does
One click locks the mouse. Your PIN unlocks it.
ASL MouseLock stops the mouse and touchpad until you type your PIN. Lock it before you hand the laptop to a child for a video, when the cat likes to walk across the desk, or during a presentation or call where a stray click would end the show.
MouseLock is a convenience lock, not a replacement for the Windows lock screen: Ctrl+Alt+Del always works, so you can never be locked out of your own PC. To secure your PC, press Windows+L.
Want to lock it from your phone? See ASL MouseLock Remote.
In the app
- Lock from the tray icon, with Ctrl+Alt+M, or automatically after a few idle minutes.
- Type your PIN and press Enter to unlock. After three wrong tries it pauses before letting anyone try again.
- A small badge in the corner shows it is locked, so your video stays in view. Or cover the screens completely.
- Optional: lock the keyboard too, so only the PIN keys work.
- Starts with Windows if you want it to.
- Free. No ads, no account, no internet connection, nothing collected. Your PIN is stored only as a secure hash.
