App Lock is another useful security feature, enabling users to safeguard selected apps from unauthorized access. Users can set up a locking mechanism, such as PIN, password, pattern, or biometrics (e.g., fingerprint or face recognition on supported devices), which is required to launch a protected app. Furthermore, they might be able to customize the app locking behaviour, such as unlocking when connected to a trusted Wi-Fi or locking based on location or time schedule.
