Lock screen timeout determines how long your computer waits while idle (i.e., when no mouse or keyboard input is detected) before activating the lock screen.
How to Change the Lock Screen Timeout Setting in Windows 11
You can change the amount of inactivity that must pass before Windows locks your screen. Here’s what you need to know.
The lock screen timeout in Windows 11 is the setting that determines how long the system waits during inactivity before displaying the lock screen. It is designed to help secure your device by locking it when not in use and to save power, especially on battery-powered devices.
A shorter timeout improves security and saves power by locking the device sooner during inactivity. A longer timeout keeps the device accessible for longer periods, but reduces security and increases power consumption.
