title: How to reenable FaceID on iPhone X simulator

  <p>It appears <a href="https://www.iphonelife.com/content/how-to-turn-face-id-apps-settings-iphone-x" rel="nofollow noreferrer">in this article</a>, that the ability to update FaceID settings for a specific app is possible, however this does not seem to be the case in the iPhone X simulator (xCode version: 9.2).</p>
  
  <p>The only other setting that appears in the same sub-list as the "General" category is "Privacy", and it does not appear to be under the app's settings.</p>
  
  <p>Ultimately, I am trying to test a workflow for when the user is attempting to re-enable FaceID for my react-native app, once they've left and come back.</p>
  
  <p>Does anyone know how to enable to FaceID settings in the simulator's settings, or change the preferences while the app is still installed and backgrounded on the device?</p>
