How to Enable or Disable Face Recognition for Apps on Samsung Phones (One UI)

 

Samsung smartphones running One UI offer advanced Face Recognition technology, which not only unlocks your device but can also secure apps and authorize digital payments. Properly managing Face Recognition access ensures your sensitive apps stay protected while providing fast and convenient authentication.

In this detailed guide, we’ll explain how to enable or disable Face Recognition for specific apps on Samsung devices, plus advanced tips, practical examples, and best practices for security.

Did you know? For a complete guide on this topic, check out the Samsung Learning Hub and explore related tips in the Security & Privacy Topic Hub.

🔹 1. How to Check if Face Recognition is Active

Before managing app access, you need to verify that Face Recognition is enabled and properly configured.

  1. Open Settings → Biometrics and security → Face recognition.

  2. Enter your PIN, Pattern, or Password to access Face Recognition settings.

  3. You can see if Face Recognition is currently active and view existing profiles.

  4. Options include:

    • Faster recognition: Increases unlock speed but slightly reduces security.

    • Require eyes open: Ensures the device only unlocks when your eyes are open.

    • Alternate appearance: Allows you to register a second facial profile for better recognition under different conditions.

💡 Pro Tip: For optimal security, combine Face Recognition with a PIN, password, or pattern, especially if you’re enabling access for banking or payment apps.

🔹 2. How to Enable or Disable Face Recognition for Specific Apps

Samsung allows certain apps to authenticate using Face Recognition. This is particularly useful for banking, messaging, and payment apps, but you can control which apps have access.

Steps:

  1. Go to Settings → Biometrics and security → Other apps.

  2. You’ll see a list of apps that support Face Recognition.

  3. Toggle the switch ON to enable Face Recognition for an app, or OFF to restrict it.

🔹 Practical Examples:

  • Banking & Finance Apps: Enable Face Recognition for fast, secure access without typing passwords.

  • Messaging & Social Media Apps: Disable Face Recognition if you prefer additional privacy. Logging in requires a password or PIN.

  • Samsung Pay & Digital Payments: Enabling Face Recognition allows quick and secure transactions.

💡 Pro Tip: Only enable Face Recognition for apps you trust and avoid using it for apps with highly sensitive data if multiple people may have access to your phone.

🔹 3. How to Use Alternate Appearance for Better Recognition

Face Recognition can struggle in certain conditions, such as low light, wearing glasses, or using a mask. Samsung’s Alternate Appearance feature helps improve recognition reliability.

Steps:

  1. Open Settings → Biometrics and security → Face recognition.

  2. Tap Alternate appearance → Add.

  3. Follow the on-screen instructions to register a second facial profile.

This ensures smoother Face Recognition for apps and device unlocking in a wider range of real-life situations.

🔹 4. How to Remove Face Recognition Access from an App

You can revoke Face Recognition permissions for individual apps anytime to improve security or privacy.

  1. Go to Settings → Biometrics and security → Other apps.

  2. Find the app in the list.

  3. Toggle OFF to remove Face Recognition access.

This guarantees that access to the app will now require a password, PIN, or pattern instead of your face.

💡 Pro Tip: Revoking access is particularly important if you temporarily lend your phone to someone else or if you stop using an app.

🔹 5. How to Re-enable Face Recognition for Apps

If you previously disabled Face Recognition but want to reactivate it:

  1. Go to Settings → Biometrics and security → Other apps.

  2. Toggle ON for the desired app.

  3. Open the app to confirm Face Recognition is functioning properly.

Some apps may require logging out and back in to refresh Face Recognition permissions.

🔹 6. Important Security Notes for Face Recognition

  • Security Limitations: Face Recognition on Samsung devices can potentially be bypassed with photos or similar-looking faces. Always pair it with a PIN, password, or pattern for maximum protection.

  • Low Light Conditions: Face Recognition may fail in dim lighting or if your eyes are not clearly visible.

  • Privacy Considerations: Enabling Face Recognition for apps makes them accessible to anyone whose face matches your profile. Disabling it ensures app access only through a secure alternative authentication method.

💡 Pro Tip: Avoid enabling Face Recognition for apps that handle highly sensitive data if your phone is often shared with others.

🔹 7. How to Troubleshoot Face Recognition Issues

Face Recognition may sometimes fail due to software glitches or environmental factors. Here’s how to troubleshoot common problems:

  • Face Not Recognized: Clean the front camera lens and ensure your face is fully visible.

  • App Fails to Authenticate: Check that the app supports Face Recognition and toggle the switch in Other apps settings.

  • Poor Performance in Low Light: Enable Alternate appearance or combine with PIN/Pattern unlock.

  • Recognition Fails After System Update: Re-register your face or reset Face Recognition settings.

🔹 8. How to Optimize Face Recognition for Maximum App Security

  1. Always combine Face Recognition with a strong PIN, password, or pattern.

  2. Enable Require eyes open for sensitive apps like banking.

  3. Use Alternate Appearance if you frequently wear glasses, hats, or masks.

  4. Regularly review Other apps in settings to ensure only trusted apps have access.

  5. Avoid enabling Face Recognition for apps with highly sensitive personal or financial data unless absolutely necessary.

💡 Pro Tip: Samsung Pay and financial apps often have additional security layers. Even with Face Recognition enabled, some apps may ask for a PIN or OTP for large transactions.

🔹 9. Summary: How to Enable or Disable Face Recognition for Apps on Samsung

To manage Face Recognition on your Samsung device safely:

  1. Verify Face Recognition is Active: Settings → Biometrics and security → Face recognition.

  2. Enable or Disable Apps: Settings → Biometrics and security → Other apps → Toggle ON/OFF.

  3. Use Alternate Appearance: Improve recognition under varying lighting and appearances.

  4. Remove or Re-enable Apps: Adjust app access anytime.

  5. Follow Security Best Practices: Combine Face Recognition with PIN/Pattern and review app permissions regularly.

By following these steps, you can fully control which apps use Face Recognition, ensuring convenience and privacy without compromising security.
