To put Face ID on Snapchat, you need to enable the App Lock feature within the app's settings, which will require your face scan to open the app or view private content. This adds an extra layer of privacy beyond your phone's lock screen, ensuring only you can access your Snaps and messages. You can similarly put face id on Facebook to lock down Messenger chats from prying eyes.
How to put a Face ID on Snapchat
This guide covers locking the Snapchat app itself with Face ID for privacy, not for logging into your account. Snapchat also supports Passkeys for account login, which can use Face ID, but that is a separate feature for signing in, not for locking the app after it is open.
Step 1: Update the Snapchat app
Ensure you have the latest version of Snapchat installed from the App Store. Snapchat regularly releases updates with new features and bug fixes, and the App Lock feature requires a current version to work properly.
Step 2: Enable Face ID on your iPhone
Before you can lock Snapchat with Face ID, you must verify that device-level Face ID is set up. Open your iPhone's Settings app, tap "Face ID & Passcode," and enter your passcode. Confirm that "iPhone Unlock" is toggled on, or use face id instead of passcode if you currently rely on a numeric entry. This step is essential for the app to recognize your face.
Step 3: Open Snapchat and access settings
- Open the Snapchat app on your iPhone.
- Tap your Bitmoji or profile icon in the top-left corner to go to your profile screen.
- Tap the gear icon in the top-right corner to enter Snapchat's settings menu.
Step 4: Enable 'App Lock'
- In Snapchat's settings, scroll down to the "Privacy Controls" section.
- Tap "App Lock."
- Toggle the switch to turn on App Lock.
- Select "Use Face ID" as the verification method. You may be prompted to authenticate with your device's Face ID to confirm the change.
Once enabled, the App Lock feature will require Face ID each time you open Snapchat or access private content like Memories. You can revisit the App Lock menu at any time to adjust preferences, giving you full flexibility in using and managing Face ID.
Step 5: Test the Face ID lock
- Close the Snapchat app completely by swiping it away from your app switcher.
- Reopen Snapchat by tapping its icon.
- A Face ID scan prompt should appear. Look at your iPhone to unlock the app.
- Confirm that the scan works correctly and grants you access to your account.
If the prompt does not appear, double-check that App Lock is toggled on in Snapchat's settings and that Face ID is enabled on your device. Testing ensures the lock is active and functioning as expected for your privacy.
