Apple has built what many consider the most private mainstream mobile platform, giving users control over data permissions and limiting third-party app access to sensors and files without explicit consent. But beyond privacy, iOS includes safety features that can help during emergencies or protect data if an iPhone is lost or stolen. Some work automatically, though several require manual setup. Here’s what to enable.
Strengthening account recovery and iCloud protection
The Apple Account acts as the key to a user’s digital life, controlling iCloud data, passwords, app purchases, and more.
Losing access can be costly.
In Settings, tap your name, then Sign-In & Security, and head to Two-Factor Authentication. Add a trusted phone number or two. That way, even without an Apple device, you can receive a verification code via SMS.

On the same screen, choose a recovery contact — a trusted friend or family member. If you get locked out, they can help you regain access.
iCloud backups are the default for storing phone data, syncing photos, contacts, notes, messages, and more across its devices. Open the Settings app, tap iCloud, and enable toggles for the apps you want backed up.
For full device backups, that’s also under iCloud. Once that’s done, consider enabling Advanced Data Protection for end-to-end encryption, and disable iCloud.com if you never use the web interface. iCloud+ subscribers should also turn on Hide My Email and Private Relay for extra privacy when signing up for accounts or browsing in Safari.
Biometrics, emergency tools, and location defense
Using a passcode as the primary lock is risky — people can watch you type it. Biometric authentication is safer and more convenient. Go to Face ID & Passcode, set up Face ID, and scroll down to disable access to Notification Center, Control Center, Wallet, and other sensitive menus when the device is locked.
At the bottom, turn on Erase Data, which wipes the smartphone after ten wrong passcode attempts. The device stays locked and tied to your account, but brute force attacks won’t expose your data.

Emergency situations can happen anytime. In Emergency SOS (below Face ID & Passcode), make sure the shortcut to call emergency services is enabled. Also turn on Crash Detection, which automatically calls emergency services and notifies contacts if a severe car crash is detected.
To add or adjust emergency contacts, go to Health and tap Edit Emergency Contacts.
For defense against loss or theft, Find My is essential. Go to Settings > your name > Find My > Find My iPhone, and enable Find My iPhone, Find My network, and Send Last Location.
Limiting app permissions and hiding sensitive apps
Apps on the device can’t access photos, contacts, location, camera, or microphone without permission. To review and revoke what you’ve already granted, go to Privacy & Security in the Settings menu and check each section.
If you suspect a sophisticated cyberattack, enable Lockdown Mode at the bottom of the same screen — it restricts certain phone features as a last resort. Alternatively, use Safety Check > Emergency Reset to quickly revoke app permissions and stop sharing information in Health, Fitness, and Find My.

To hide or lock an app, tap and hold its icon on the Home Screen and select Require Face ID. If the app supports it, you can also choose Hide and Require Face ID, which moves it to a concealed Hidden folder in the App Library. Most apps offer this option except harmless ones like Camera and Settings.
Stolen Device Protection, passwords, and updates
Stolen Device Protection prevents a thief who knows your passcode from taking over your device. Sensitive changes — like resetting the device — require a Face ID scan followed by a one-hour delay, giving you time to remotely secure the phone via Find My on another device. Enable it under Privacy & Security, at the bottom.
If you’ve been storing login credentials in Notes, switch to the built-in Passwords app. It’s more secure and can generate two-factor authentication codes and store passkeys, which you should enable for all eligible accounts to maximize security.
Operating system updates deliver important security patches that prevent hackers from exploiting vulnerabilities. To get them automatically, go to General in the Settings app, tap Software Update, then Automatic Updates and enable Automatically Install. Also under Privacy & Security, find Background Security Improvements and ensure Automatically Install is toggled on.
