Some Android devices automatically enable you to authenticate using your Android Wear OS wearable (I.E. Watch).
If the PingID mobile app is installed on your device, your Wear OS device and its configuration must be compatible with the PingID mobile app. If so, you'll automatically start receiving push notifications to your Wear OS device when your phone is locked.
If your Android device and its configuration support the use of Wear OS wearables (I.E. Watches) for notifications, you will receive a notification to your watch automatically when your phone is locked.
The ability to authenticate using a Wear OS device varies according to your specific Android device's model and configuration.
