A screen lock is a security feature that prevents unauthorized access to a device. It can be set up using a password, PIN, pattern, or biometric data such as a fingerprint or face scan. Screen locks are important because they help to protect personal data and prevent the device from being used by unauthorized individuals.
The iPhone has a variety of screen lock options available. To set up a screen lock, go to the Settings app and tap on “Face ID & Passcode” or “Touch ID & Passcode”. From here, you can choose the type of screen lock you want to use and set it up.
