It's no secret that the iPhone is a popular smartphone. It’s like having a mini computer at your fingertips. Unfortunately, hackers love to target smartphones to steal financial data and personal information.

Since smartphones make it so simple to do daily tasks from anywhere, they also give cybercriminals an easy way to invade your privacy. There are settings that could allow unauthorized access to your device if they’re not secure. Even tech-savvy users could be at risk.

Don’t be alarmed, because there are steps you can take to prevent hackers from gaining access to your iPhone. Keep reading our guide to the 21 iPhone privacy settings you need to change for better security, plus the best VPNs for iPhone to secure your Wi-Fi against trackers.

How secure is your iPhone?

If you think your iPhone is secure, you may be interested to know Apple disclosed some security vulnerabilities that could allow hackers to take control of the device. There have been two security reports released by Apple stating that these issues could give full admin access to the devices and allow intruders to impersonate the owners.

Apple maintains control over the app store, but for people who use jailbreaking to install other apps, that may not matter. Jailbreaking modifies the operating system, giving you more access to the entire device and what’s on it. Jailbreaking your iPhone security won’t just void your warranty, it will also expose your device to possible malware.

You can prevent these risks by changing your iPhone settings. We’ll cover the most critical ones to adjust to keep your popular smartphone secure.

Login security settings

One of the best ways to secure your iPhone is to start with how you log in to the device. You want to restrict the settings so that you are the only one who knows how to log in to your phone.

1. Create a strong passcode

When you create a passcode for your phone, you’ll want to use something others won’t be able to guess. A passcode is usually four to six digits and is a number you set up as another layer of security. You also want strong passwords to access sites you visit from your iPhone.

Your iPhone will identify weak passwords that may have been used numerous times or are easy for others to figure out. Your iPhone will also monitor your passwords in case they show up in known data leaks. It’s a good rule of thumb to use a combination of letters, numbers, and characters.

Alternatively, you can let Apple recommend a password for you by going into your Settings. To check if your passwords are strong, go into Settings, then scroll down to Passwords.

2. Set up biometric authentication

You can set up the Touch ID sensor on your iPhone to be sure you’re the only one who can access your device. Your fingerprint will identify you and make it simple to get into your smartphone. You can do this from your Settings menu.

1. From Settings, go to Touch ID & Passcode, then enter your passcode.
2. Tap Add a Fingerprint and hold your device as you usually do when touching the Touch ID sensor.
3. Touch the sensor with your finger for the device to recognize your fingerprint. Hold it there until you feel a quick vibration or until your iPhone instructs you to remove your finger.
4. If your device doesn’t have Touch ID and instead shows Face ID, you can use your face to unlock your iPhone by following the same steps and selecting Face ID & Passcode.

3. Enable two-factor authentication

Two-factor authentication (2FA) gives you an extra layer of security for your iPhone. When you use this process, you don’t rely solely on your strong password. 2FA adds more security between you and a hacker by requiring you to enter a code within a specified time frame. If you don’t enter the code correctly at that time, you won’t get access to your device.

When you use 2FA, you’ll enter two pieces of information: your regular password and then a six-digit verification code sent to your phone number. Here’s how to set it up:

1. Go to Settings, [Your Name], then Password & Security.
2. Tap on Turn On Two-Factor Authentication and tap Continue.
3. Enter the phone number where you want to receive the codes when you sign in.
4. Click Next and enter the code to verify the phone number, then turn on 2FA.

4. Use the “Sign in with Apple” option

This is another security feature you can use to sign in to different accounts. With this option, you can use the Sign in with Apple button on participating websites or apps. It shows that you’re using a secure Apple ID, and you won’t need to use a separate password.

1. When you have a participating app or website, click the Sign in with Apple button.
2. Enter the information required.
3. Tap Continue and confirm with Touch ID, Face ID, or your iPhone passcode.

5. Restrict lock screen access

You can control access to different items when your iPhone is locked. When you turn off Lock Screen access, you prevent someone else from viewing your information. To restrict lock screen access:

1. From Settings, go to Face ID & Passcode.
2. Choose the options below Allow Access When Locked.
3. You’ll get a list of features you can turn off or access when your iPhone is locked.

6. Review notification privacy settings

Notifications help you keep track of missed calls, event data, and other happenings. You can customize these to control the notifications you receive.

Some apps use your location data to send you alerts. Others can also send you marketing messages. You should turn off these notifications for better privacy.

1. From Settings, go to Notifications.
2. View notifications in a list.
3. Here you can choose when you want a notification to appear or if you need to stop getting them altogether.
4. If you want to turn off notifications for different apps, go to Settings > Notifications > Siri Suggestion, then turn off any app.

iOS app settings

You may want to adjust your iOS app settings to reflect your security needs. There are options you can use to tailor individual app settings just for you.

2. Click on Find My.
