Lock Screen

The Lock Screen is the first screen presented to a user before access is granted to an iOS or iPadOS device. If a passcode is set, the data on the device will be encrypted and a 4 or 6-digit numeric will be required. Face ID and Touch ID can be used to unlock devices that support biometric identification.

History
Starting with iOS 10 in 2016, an Apple device without a passcode will present "Press Home to unlock" instead of "Slide to unlock".

In 2022, iOS 16 added the ability to customize the Lock Screen with TrueDepth images and widgets.
