Your Device's Unlock Pattern, Pin, or Password Feature
You can increase your device’s security by creating a screen unlock pattern (disabled by default), by creating a PIN, or by choosing a password. When these features are enabled, you must draw the correct unlock pattern, enter the PIN, or enter the password on the screen to unlock and regain access to the device.
