Basics
Changing the screen lock method
To change the screen lock method, launch the Settings app, tap Lock screen → Screen lock
type, and then select a method.
When you set a pattern, PIN, password, or your biometric data for the screen lock method,
you can protect your personal information by preventing others from accessing your device.
After setting the screen lock method, the device will require an unlock code whenever
unlocking it.
You can set your device to perform a factory data reset if you enter the unlock code
incorrectly several times in a row and reach the attempt limit. Launch the Settings app,
tap Lock screen → Secure lock settings, unlock the screen using the preset screen lock
method, and then tap the Auto factory reset switch to activate it.
