# Tự động khoá màn hình

When you leave your computer, you should lock the screen to prevent other people from using your desktop and accessing your files. You will still be logged in and all your applications will keep running, but you will have to enter your password to use your computer again. You can lock the screen manually, but you can also have the screen lock automatically.

Nhấn chọn tên bạn trên thanh đỉnh và chọn Thiết lập hệ thống.

Open Screen.

Make sure Lock is switched on, then select a timeout from the drop-down list below. The screen will automatically lock after you have been inactive for this long. You can also select Screen turns off to lock the screen after the screen is automatically turned off, controlled with the Turn off after drop-down list above.
