Fingerprint/FaceID is the optional third factor of authentication. This feature can be turned on by first navigating to the settings menu within the Arculus app by tapping on the gear icon within the app. Then in the settings menu, navigate to the 'Authorization' section and toggle the 'Activate 3FA' switch to the “on” position. Once the feature is turned on, a fingerprint or FaceID will be required to open the Arculus Wallet^TM App and get to your “Wallet.” This feature can also be turned off by toggling the 'Activate 3FA' switch to the “off” position.
