Lock screen

Lock screen may refer to either of the following:

1. Also called a login screen, a lock screen is an interface on a computer, smartphone, or tablet that appears upon startup. Access to all the device's applications is limited while locked to prevent access by unwanted users. When a password is entered or the device is unlocked with biometrics, the home screen, desktop, or app launcher is displayed, and the device's contents become available.

Most lock screens feature a customizable wallpaper that can be changed from what is displayed on a home screen or desktop. The lock screen on mobile devices also displays the current date and time with any text messages, missed calls, or other notifications. Notifications can also be selected to launch an individual application once the device is unlocked. Most smartphone lock screens also allow users to access the camera and make emergency phone calls, even while the device is secured.

Why does a smartphone need a lock screen?

Smartphones have a lock screen for the following reasons:

• If password-protected, the lock screen helps prevent unauthorized access and use by others.
• A lock screen helps prevent unwanted pocket dialing, text messages, or actions in apps while the phone is not in use.

How do I adjust the lock screen settings?

How is the lock screen different than the home screen?

The lock screen has limited options. For example, the lock screen on an iPhone has the date, time, and any recent notifications. The home screen shows all available apps and widgets, and lets you access all other smartphone areas. See our home screen page for further information and an example of the home screen.

2. With Microsoft Windows, the lock screen is a feature that secures the computer with a password to protect it while you're away. Windows 8 updated the lock screen to display a lock screen image(s), time and date, and apps (e.g., calendar, messages, and mail) while the computer is locked. The picture below is an example of the Windows 10 lock screen.

Getting out of the lock screen

Lock screens can be exited using multiple methods. Press the spacebar, press Enter, or put your finger on a touch screen and swipe towards the top. If the lock screen has a password, it must be entered correctly to move past the lock screen.
