Top iPhone Security Tips You Should Know in 2025

by

In today’s increasingly digital world, securing your iPhone is more important than ever. Whether you’re protecting personal data, banking apps, or private photos, iPhone users must stay proactive to prevent cyber threats. Apple continues to enhance iOS security, but there are still key steps you should take to stay protected.

In this guide, we’ll explore the top iPhone security tips for 2025 and how you can easily apply them.

1. Use a Strong Passcode (Not Just Face ID)

While Face ID and Touch ID are convenient, a strong passcode is still essential. Avoid using simple numbers like “1234” or birthdays. Instead:

  • Use a 6-digit alphanumeric code.
  • Avoid repeating digits or patterns.
  • Enable “Erase Data” after 10 failed passcode attempts under Settings > Face ID & Passcode.

2. Keep iOS Updated

Apple regularly releases iOS updates that patch security vulnerabilities. In 2025, staying on the latest iOS version is critical.

  • Go to Settings > General > Software Update to check manually.
  • Enable automatic updates for both iOS and app updates.

Bonus Tip: Also update your apps frequently, as they may contain fixes for known security flaws.

3. Review App Permissions

Some apps request unnecessary access to your microphone, camera, or location. Here’s how to stay in control:

  • Navigate to Settings > Privacy & Security.
  • Review which apps access Camera, Microphone, Contacts, Location, etc.
  • Disable permissions for apps that don’t need them.

4. Use Apple’s Advanced Data Protection (iCloud Encryption)

Starting with iOS 17 and beyond, Apple offers Advanced Data Protection for iCloud. This end-to-end encryption protects your data from unauthorized access—even Apple can’t decrypt it.

To enable:

  • Go to Settings > [Your Name] > iCloud > Advanced Data Protection.

This encrypts:

  • Messages backups
  • Photos
  • Notes
  • Device backups

5. Enable Two-Factor Authentication for Apple ID

2FA adds an extra layer of protection to your Apple ID and iCloud account. Always use two-factor authentication (2FA) and verify trusted devices regularly.

  • Go to Settings > [Your Name] > Password & Security.
  • Ensure 2FA is On and add backup phone numbers just in case.

6. Activate Lockdown Mode (For High-Risk Users)

If you’re a journalist, government official, or feel at risk of sophisticated cyberattacks, Lockdown Mode offers extreme protection.

To enable:

  • Go to Settings > Privacy & Security > Lockdown Mode.

What it does:

  • Blocks message attachments
  • Limits web browsing features
  • Disables FaceTime from unknown numbers

This feature is available starting from iOS 16 and now improved in iOS 18 (2025).

7. Use a Private Relay or VPN for Browsing

iCloud Private Relay helps hide your IP address and browsing activity in Safari.

To activate:

  • Go to Settings > [Your Name] > iCloud > Private Relay.

Alternatively, consider a trusted VPN app if you use third-party browsers or need more flexible location options.

8. Disable USB Accessories When Locked

Hackers may use USB accessories to access your phone without your knowledge.

  • Go to Settings > Face ID & Passcode.
  • Scroll to USB Accessories and toggle Off.

This prevents unauthorized devices from connecting when your iPhone is locked.

9. Turn Off Location Services for Unnecessary Apps

Too many apps track your location, which can be risky. To limit this:

  • Go to Settings > Privacy & Security > Location Services.
  • Set apps to “While Using” or “Never”.
  • Use Share My Location only when necessary.

10. Use Built-In Password Manager (Keychain)

Stop using the same passwords for every app or website. Apple’s iCloud Keychain helps store strong, unique passwords securely and alerts you of breaches.

  • Manage it via Settings > Passwords.
  • Enable Security Recommendations for compromised passwords.
