Privacy and Security Settings

These days, privacy and security come first no matter if you’re using a laptop or phone.

These settings on your iPhone 16 give you more control over who sees your data. They work quietly in the background. And most users notice the difference right away once these setting applied.

Having said that, we can start with the ones that protect your apps and screen without much hassle.

1. Lock or Hide Apps

Here comes the most important one. You can lock or hide apps with Face ID from the home screen your iPhone 16. This keeps banking or private apps safer if someone borrows your phone. It works well on iOS 26.

You can follow these steps to set it up.

1. Long-press the app icon on your home screen.
2. Tap Require Face ID from the menu that appears.
3. Choose Require Face ID or Hide and Require Face ID.

Once applied, the hidden apps move to a locked folder in the App Library. You can unlock it with Face ID or your passcode when needed.

We have found this helpful for shared family devices. Spotlight search may still find hidden apps. So, you can test it with a non-critical app first.

2. Control Access on Lock Screen

You can decide what appears on the lock screen. So, this reduces accidental taps or unwanted glances. To put it simply, it adds a simple layer of privacy.

You can follow these steps to adjust it.

1. Go to Settings and tap Face ID & Passcode.
2. Enter your passcode when prompted.
3. Scroll to Allow Access When Locked and toggle items off.

You can turn off Notifications or Control Center from there. This change takes effect immediately.

You still see the time and wallpaper. However, many people turn off Control Center access for extra safety in public.

3. Use Private Wi-Fi Address

Do you know that your iPhone can rotate its Wi-Fi address on each network? Yes, that’s right, it can do that. This makes tracking harder across locations. This helps on public or shared Wi-Fi.

You can follow these steps to turn it on.

1. Open Settings and tap Wi-Fi.
2. Tap the (i) next to your network name.
3. Toggle Private Wi-Fi Address on.

You can do this per network if you want. Some captive portals may need the toggle off temporarily.

You can turn it back on after you connect, while the privacy gain stays worth the small effort.

4. Enable Developer Mode (Use with Care)

Just like the Developer Options on Android phones, iPhone users get similar too.

Developer Mode can open advanced options for testing apps. While most everyday users do not need it, truth be told, you can turn it on only if you sideload software.

You can follow these steps if you need it.

1. Go to Settings and tap Privacy & Security.
2. Scroll down to Developer Mode.
3. Toggle the switch on after any prompt.

You may need Xcode or a configuration profile first. We recommend caution here as it can increase security risks if misused.
