How to lock an app with Face ID on iPhone using iOS 18

How to lock an app with Face ID on iPhone using iOS 18 has been a question on iOS user’s mind, this post reveals exactly how to lock an app with Face ID on iPhone using iOS 18.

Apple’s iOS 18 brings a powerful and much-anticipated feature that gives users more control over their device’s security: app-specific Face ID locking. In a world where smartphones carry both private and professional lives in a single device, securing individual apps with Face ID adds an extra layer of peace of mind.

Why Lock Individual Apps with Face ID?

Locking specific apps, especially those that contain sensitive data, has been in high demand for iPhone users. Until recently, securing apps was limited to device-wide locking.

With iOS 18, Apple extends Face ID to protect specific apps, making it perfect for users who share their phone with family or friends or just want added control over sensitive apps.

Apps like messaging, banking, and email can now have an additional Face ID layer, reducing the chance of unauthorized access even if someone unlocks your device.

Here’s a step-by-step guide to setting up app-specific Face ID locks on iOS 18.

Step-by-Step Guide: How to lock an app with Face ID on iPhone using iOS 18 / Enabling Face ID for Individual Apps in iOS 18

iOS 18 has made it easy to lock individual apps using Face ID, and you can set it up in just a few minutes. Follow these steps:

  1. Open Settings
    • Begin by opening the Settings app on your iPhone.
  2. Navigate to Privacy & Security
    • Scroll down and tap on Privacy & Security. Here, you’ll find the newly added App Lock option.
  3. Select the Apps You Want to Lock
    • Tap App Lock, where you’ll see a list of compatible apps installed on your device.
    • Turn on the toggle next to each app you want to lock with Face ID.
  4. Confirm with Face ID
    • Once you’ve selected the apps, iOS will prompt you to confirm your choice using Face ID.

    Now, whenever you or anyone else tries to open the secured app, Face ID verification will be required.

Advanced Security Customizations in iOS 18

iOS 18 includes additional security customizations, providing users with more control over when and how apps are locked. Here’s a quick overview of some of the advanced options:

  • Time-Based and Location-Based App Locking: iOS 18 introduces customizable controls that let users lock specific apps automatically based on time or location. This means, for instance, you can set social media apps to lock during work hours or keep certain apps locked while at home, enhancing both security and productivity.
  • App Locking and Hiding: Users can now lock individual apps by requiring Face ID or Touch ID to access them, adding an extra layer of security against unauthorized access. Additionally, for even greater privacy, iOS 18 lets you hide apps from your home screen entirely. Hidden apps are only accessible via the “Hidden Apps” folder, which requires Face ID or Touch ID to open, helping keep sensitive apps, such as financial or personal ones, out of sight when your phone is shared.
  • Notification Privacy: To prevent sensitive information from displaying on the lock screen, iOS 18 hides notification content for apps locked with Face ID. Only once the app is unlocked will the notification’s content be visible, ensuring that private details remain secure.
  • Passwords App: iOS 18 debuts a dedicated Passwords app, offering a centralized hub for managing and securing passwords across Apple devices. This app includes features such as compromised password alerts, two-factor authentication support, and management of Wi-Fi credentials. These options elevate password security and streamline password management, providing alerts for weak or compromised passwords, which helps mitigate risks associated with data breaches.

Popular Apps to Secure with Face ID

Some apps are especially beneficial to secure with Face ID, particularly those that manage private or sensitive data:

1. Messaging Apps

Messaging apps are often the hub of private conversations, and it’s essential to keep this data secure. Popular messaging platforms like WhatsApp, Telegram, and Messages store a variety of sensitive content, from private conversations to photos and documents.

While apps like WhatsApp have their own in-app Face ID locking feature, iOS 18’s expanded security options mean you can extend Face ID protection to any messaging app on your device.

By setting Face ID as a requirement for accessing messaging apps, users prevent unauthorized access and ensure that conversations remain private, especially when their phones might be accessed by others temporarily.

2. Banking and Payment Apps

Banking apps are a prime candidate for Face ID security. With access to sensitive financial data, including account balances, transaction history, and sometimes even personal identification details, it’s critical to lock these apps securely.

Apps like PayPal, Venmo, and individual banking apps often include high-risk information that would be highly damaging if compromised.

Face ID security is an excellent way to add an extra layer of protection beyond a simple PIN or password. Financial apps are more secure than ever with iOS 18, which ensures that no one can open these apps without biometric verification.

For banking and finance apps that may not support Face ID natively, iOS 18’s Face ID customization allows you to apply this lock across any financial application on your device.

3. Social Media and Photo Storage Apps

Social media apps and photo storage services frequently house personal content that you may prefer to keep private. Locking Instagram, Facebook, Twitter, and even your photo gallery with Face ID can prevent unauthorized access to your personal media, whether it’s photos, messages, or videos shared privately.

This Face ID security is especially helpful for photo storage apps such as the native Photos app, Google Photos, and other gallery tools, which store sensitive images or personal videos that may not be intended for others to see.

With iOS 18, Face ID security can be enforced universally, giving users complete control over who can access their personal media content.

4. Email and Document Management Apps

Applications like Gmail, Outlook, and Google Drive or Dropbox often house sensitive work emails, personal correspondences, and private documents.

Adding Face ID security to these apps keeps your emails and documents locked behind biometric security, protecting against unauthorized access.

iOS 18’s universal Face ID feature is especially valuable for document management apps, which might not offer native Face ID protection.

This additional security ensures that all sensitive documents, from tax information to work files, are accessible only by you.

5. Health and Fitness Apps

Health and wellness apps, including Apple Health, MyFitnessPal, and Fitbit, often contain highly personal data, from exercise history to health metrics like weight, heart rate, and even medical information.

Protecting these apps with Face ID provides peace of mind and ensures that your health information remains confidential.

Apple Health, in particular, benefits greatly from Face ID security, as it stores extensive health information and can even sync with third-party apps, further expanding the breadth of data contained within.

With iOS 18’s new capability, any app managing health data can be protected with Face ID, even if it didn’t previously support it.

6. Shopping and Retail Apps

Many retail and shopping apps, such as Amazon, eBay, and Walmart, store sensitive payment information.

Locking these apps with Face ID prevents unauthorized users from making purchases or viewing payment details if they gain access to your device.

Shopping apps might not always provide biometric protection by default, but iOS 18’s flexibility allows you to secure any app containing payment or address information, giving you full control over who can access these apps.

With iOS 18’s new feature, you can protect any app, regardless of whether it has native Face ID support.

Tips for Optimizing Face ID App Lock on iOS 18

Optimizing Face ID app locking on iOS 18 can make a significant difference in securing your personal information. Here are some advanced tips to ensure maximum efficiency and protection:

1. Keep Your iOS Updated

One of the most straightforward yet effective security measures is to keep your iPhone’s software current. Apple frequently releases updates that include security patches, bug fixes, and feature enhancements, ensuring that Face ID runs optimally. Updates can improve Face ID accuracy, speed, and integration across apps. To check for updates:

  • Go to Settings > General > Software Update.
  • If an update is available, download and install it. Opt for automatic updates to ensure your device stays current without manual intervention.

By staying on top of iOS updates, you protect your device from new security vulnerabilities and optimize Face ID’s performance.

2. Enable Find My iPhone

Activating Find My iPhone is essential for securing your device if it’s ever lost or stolen. With Find My iPhone enabled, you can remotely lock or erase your device and, crucially, prevent unauthorized users from accessing your apps locked with Face ID. Here’s how to enable it:

  • Go to Settings > [Your Name] > Find My.
  • Enable Find My iPhone and, if desired, turn on Send Last Location to receive updates about your phone’s location even if the battery is low.

If your device is compromised, you can log in to iCloud.com or the Find My app on another Apple device to lock or erase it remotely.

3. Customize Your App Locks Regularly

Your security needs may change over time, and iOS 18’s app locking is flexible enough to adapt. For example, you might want to add more apps to your Face ID lock list during a busy season or remove a few if your phone is used only by you. To customize app locks:

  • Go to Settings > Face ID & Passcode.
  • Select the apps you wish to protect with Face ID and toggle them on or off as needed.

Regularly revisiting this list ensures you’re covering all important apps without over-securing less sensitive ones, balancing both security and convenience.

4. Manage Face ID Sensitivity

Face ID’s sensitivity settings are adjustable to improve accuracy and security in different scenarios. For instance, if you’re in a dim environment or wear accessories like sunglasses, Face ID may have difficulty recognizing you. To enhance Face ID’s adaptability:

  • Go to Settings > Face ID & Passcode > Require Attention for Face ID.
  • Enable Require Attention for improved accuracy, ensuring that Face ID detects your gaze before unlocking.

For added accessibility, you can disable this feature, making Face ID more flexible in challenging environments.

5. Review Your Notification Settings

Even if you’ve locked apps with Face ID, sensitive notifications can still display on your lock screen, potentially exposing private information. iOS 18 allows you to customize notification visibility based on whether Face ID is used. To adjust these settings:

  • Go to Settings > Notifications and select the app you want to manage.
  • Choose Show Previews > When Unlocked to hide the content of notifications unless Face ID is used.

This feature ensures sensitive information remains hidden, even if notifications are accidentally viewed on your lock screen.

6. Utilize Two-Factor Authentication (2FA) for Extra Security

Many apps now support Two-Factor Authentication (2FA) for added protection. Activating 2FA ensures that even if someone bypasses your Face ID, they would need a second verification step (like a one-time code sent to another device) to access your account. This setup is particularly useful for securing financial apps, email, and social media accounts.

For apps that don’t natively support Face ID, use third-party authenticator apps (like Google Authenticator or Authy) alongside Face ID for a robust security setup.

7. Explore Advanced Security Features in iOS 18

iOS 18 comes with new security customization options for Face ID that let you tailor protection even further:

  • Time-Based Locking: Schedule app locks based on time, like locking social media during work hours to avoid distractions.
  • Location-Based Locking: Set specific apps to lock or unlock based on your location, such as securing work apps when at home.
  • Notification Privacy: For apps locked with Face ID, hide notification previews until unlocked, protecting message content from prying eyes.

These options can be configured under Settings > Face ID & Passcode > App Locking Options, providing more control over your device’s security based on your lifestyle.

8. Use a Strong Passcode in Conjunction with Face ID

Face ID is highly secure, but pairing it with a strong passcode provides a solid backup. If Face ID doesn’t recognize you, the device will prompt for your passcode, which is why it’s crucial to choose one that’s hard to guess.

  • Opt for a 6-digit alphanumeric passcode instead of a simple 4-digit PIN.
  • Avoid using obvious patterns or birthdays for added security.

A strong passcode complements Face ID, making your device more resilient against unauthorized access attempts.

9. Limit the Number of Registered Faces

iOS 18 allows for a second person to be registered with Face ID, which can be useful in cases where multiple trusted users share the same device. However, this feature can also increase the risk of unauthorized access, so only add trusted faces and periodically review registered Face ID users.

10. Regularly Restart Your Device

While Face ID is designed to work seamlessly, a periodic device restart can help clear any minor glitches or lag that may impact its responsiveness. A quick restart can refresh the system, ensuring that Face ID recognition remains fast and accurate.

By following these tips, you can enhance the functionality and security of Face ID across your iPhone, ensuring it remains a robust security tool. The flexibility of iOS 18’s Face ID settings allows you to tailor security to your specific needs, balancing privacy with accessibility in a way that suits your everyday life.
