Add biometric (fingerprint) authentication in the Wellness app

The Wellness app now supports device-level biometric authentication, which you can use instead of manually entering your 4-digit PIN. 

Turn on biometric authentication in the Wellness app

1. Confirm your device's operating system supports biometric authentication:
   — Android: requires version 2.1.0.0 or higher.
   — iOS: requires version 2.0.7 or higher (for Face ID + Touch ID).
2. Install the latest version of the Walmart Wellness app.
3. Sign in and manually enter your 4-digit PIN.
4. You should see a prompt to Allow biometrics.
5. Tap Continue. 
6. Tap Ok or Enable when prompted.
   
7. You now have biometric authorization enabled!

If your device supports biometrics, but the feature is disabled:

1. Go to your device's Settings app (outside of the Wellness app). 
   — Android:  Locate the security or biometrics menu and toggle biometrics to ON.
   — iOS: Go to Settings > Face ID & Passcode.

Turn off biometric authentication in the Wellness app

If you previously turned on biometrics and wish to turn it off:

1. Open the Walmart Wellness app.
2. Confirm the biometric authorization request.
3. Tap the profile icon (top left). 
4. Tap Settings (bottom of the list).
5. Scroll down and tap enable biometrics to sign in to toggle the feature to OFF.
   
   (You can repeat these steps to toggle the feature back to ON at any time.)
