    • How to Use: Set up Face ID or Touch ID through Settings > Face ID & Passcode (iPhone X and later) or Settings > Touch ID & Passcode (earlier models).
    Best for: Enhancing security through biometric authentication that is both quick and difficult to bypass.
  2. iCloud KeychainiCloud Keychain securely stores your passwords, credit card information, and other sensitive data, and syncs them across all of your Apple devices. It ensures that you don’t need to memorize complex passwords, while keeping them secure.
    • How it works: iCloud Keychain encrypts your passwords and sensitive information using 256-bit AES encryption, which means that even Apple cannot access this data. It can also automatically fill in login credentials on websites and apps.
    • How to Use: To enable iCloud Keychain, go to Settings > [Your Name] > iCloud > Keychain, and toggle it on. You can also view and manage saved passwords in Settings > Passwords.
    Best for: Securely storing and autofilling passwords, and preventing unauthorized access to your accounts.
  3. Find My iPhoneFind My iPhone (now part of Find My app) is a location-tracking feature that allows you to locate your iPhone, iPad, or Mac in case it’s lost or stolen. You can also remotely lock or erase the device to protect your data.
    • How it works: When enabled, Find My iPhone sends location data to Apple’s servers and can display the device’s last known location on a map.
    • How to Use: Go to Settings > [Your Name] > Find My > Find My iPhone, and ensure it is turned on. You can also enable Send Last Location to send your device’s location to Apple when the battery is critically low.
    Best for: Locating lost or stolen devices and remotely securing them.
  4. App Privacy and PermissionsiOS gives users fine-grained control over the permissions apps can request. Apps need explicit user consent to access certain data, such as location, photos, microphone, and camera.
    • How it works: Each app must request permission for specific features (e.g., using the camera, microphone, or accessing location data). You can grant or deny access for each app and change these permissions at any time.
    • How to Use: To manage app permissions, go to Settings > Privacy, and review each category (e.g., Location ServicesCameraMicrophone) to see which apps have access.
