Your iPhone contains passwords, banking information, private messages, and personal photos. But some of the settings designed to protect that information are easy to overlook.
Apple has added several useful security and privacy features over the years, including protections against phone theft, unwanted tracking, and unauthorized access to apps.
The good news is that you can strengthen your iPhone’s security in just a few minutes without installing anything.
Here are seven settings worth checking.
1. Turn On Stolen Device Protection
Stolen Device Protection is one of the most important safeguards available on the iPhone.
It was introduced after thieves began stealing phones using passcodes they had secretly observed their owners entering in public.
With the feature enabled, certain sensitive actions require Face ID or Touch ID rather than allowing someone to use the device passcode.
Changing critical account settings can also trigger a one-hour security delay, making it harder for thieves to take control of your Apple Account.
To check the setting:
- Open Settings.
- Tap Face ID & Passcode.
- Select Stolen Device Protection.
- Turn it on if it isn’t already enabled.
For stronger protection, you can configure the security delay to apply Always, rather than only when your iPhone is away from familiar locations.
Newer iPhones may already have the feature enabled, but it’s worth checking.
2. Prevent Access to Control Center From the Lock Screen
Someone doesn’t need your passcode to access certain iPhone controls.
By default, Control Center can be opened from the Lock Screen, allowing anyone holding your phone to change connectivity settings.
That includes enabling Airplane Mode, which can interfere with your ability to locate a missing device.
To restrict access:
- Go to Settings > Face ID & Passcode.
- Scroll to Allow Access When Locked.
- Turn off Control Center.
You can also disable Siri access from the Lock Screen if you prefer to limit what someone can do without unlocking your phone.
3. Hide Notification Previews Until You Unlock Your iPhone
Lock Screen notifications can reveal more than you intend, including private messages and sensitive account information.
You can keep notifications visible while hiding their contents until Face ID or Touch ID authenticates you.
Go to Settings > Notifications > Show Previews and select When Unlocked.
You’ll still know when a notification arrives, but its message content won’t be displayed to someone looking at your locked iPhone.
4. Review Which Apps Can Access Your Location, Camera, and Microphone
Apps sometimes request more permissions than they actually need.
Apple provides tools to review what information you’ve shared and limit unnecessary access.
Open Settings > Privacy & Security > Safety Check to review sharing and access permissions.
For location permissions, visit Settings > Privacy & Security > Location Services and select individual apps.
Consider switching apps from Always to While Using the App when continuous location access isn’t necessary.
You can also disable Precise Location for apps that only need an approximate location, such as certain weather services.
For additional visibility, enable App Privacy Report under Privacy & Security. It shows how frequently apps access sensitive permissions and contact network domains.
5. Stop Apps From Tracking You Across Other Apps and Websites
Some apps collect information about your activity across other companies’ apps and websites for advertising purposes.
Apple allows you to decline these tracking requests automatically.
To disable them:
- Open Settings > Privacy & Security.
- Tap Tracking.
- Turn off Allow Apps to Request to Track.
You can also limit Apple’s personalized advertising separately under Settings > Privacy & Security > Apple Advertising > Personalized Ads.
These controls reduce certain forms of advertising tracking, although they don’t prevent every kind of data collection.
6. Lock Sensitive Apps With Face ID
Even when your iPhone is unlocked, you can require biometric authentication before opening individual apps.
This is particularly useful for banking apps, private messaging services, or anything containing sensitive personal information.
To lock an app:
- Find the app on your Home Screen.
- Touch and hold its icon.
- Tap Require Face ID.
- Confirm your selection.
Supported apps can also be hidden, removing them from the Home Screen and placing them in a protected Hidden folder in the App Library.
Keep in mind that hiding an app can affect how its notifications appear, and not every app supports hiding.
7. Check Your Security Settings Before Selling Your iPhone
If you’re planning to sell, trade in, or give away your iPhone, make sure you can complete Apple’s device preparation process.
Stolen Device Protection can require additional authentication or a security delay when changing important account settings, particularly away from familiar locations.
Before handing over your device, follow Apple’s erase and transfer instructions under Settings > General > Transfer or Reset iPhone.
You may need to complete security verification before signing out of your Apple Account or turning off Find My.
Completing those steps in advance can prevent delays when transferring the phone to its next owner.
These settings won’t eliminate every security risk, but they can make it considerably harder for someone to access your personal information if your iPhone is lost or stolen.
