A lock screen is the security interface displayed on a smartphone, tablet, or computer when the device is idle or powered on, requiring authentication before granting access. Lock screens display the time, date, notifications, and often a background image. For creators producing mobile content, lock screen aesthetics and notification management are relevant to understanding how audiences interact with content alerts. Lock screens can be customized with widgets and wallpapers, and some creators design branded lock screen wallpapers as fan engagement assets.
