Using FaceID to enhance Messenger security is crucial for iPhone users. In this article, Mytour shares a simple guide on how to lock Messenger on your iPhone using FaceID and a password.

1. Why Use Face ID to Lock Facebook Messenger?
Previously, iPhone users couldn’t utilize advanced security features to lock Messenger, leading to privacy concerns and data leaks. However, the latest update now allows users to lock Messenger directly with FaceID. This means even if you forget to lock your phone, strangers cannot access your Messenger without your FaceID. This feature has gained popularity among younger users, who value enhanced privacy and protection against unauthorized access to their messages.

Locking Facebook Messenger with Face ID offers various benefits, especially when lending your phone to others. By enabling Face ID, you can confidently share your device without worrying about others snooping on your private messages.
Activating Face ID unlock for Messenger enhances security but can occasionally complicate usage. For instance, every time you read a message or switch to another app, you’ll need to unlock Messenger again using your face. Despite this, enabling Face ID is still recommended to prevent unauthorized access to your chats.
2. How to Enable Face ID Lock for Facebook Messenger
To lock Messenger, ensure you’ve updated the app to the latest version, which includes advanced security features. The newest Messenger update introduces Face ID locking, providing an additional layer of protection for your conversations.
Step 1: Open the Messenger app, select the Options tab (1), and then choose Settings (2) to configure the app.

Step 2: Next, navigate to Privacy & Safety ➨ App Lock ➨ Enable Require Face ID.

When you enable the Require Face ID feature, the system will prompt you to confirm your face and unlock the device once to register the changes.
Step 3: Once you’ve successfully activated Face ID lock for Messenger, you’ll need to set the lock duration for when you exit the app.

- After I leave Messenger: The app locks immediately, requiring facial recognition to unlock and use it again.
- 1 minute after leaving: If you exit Messenger for 1 minute, the next use will require facial authentication to unlock.
- 15 minutes after leaving: Messenger automatically locks after 15 minutes of inactivity.
- 1 hour after leaving: The app will lock with Face ID after being inactive for 1 hour.
Step 4: You’ve now successfully enabled Face ID lock for Messenger. Once activated, every time you open Messenger, you’ll need to unlock it using facial recognition or your phone’s password.
