If you log out of the Realm app, power off (or lose power) to your phone, or cancel a log-in while in progress, the biometrics feature will be deactivated.
To prevent disabling fingerprint or face ID login, you should only swipe the app closed. Do not choose "log out" from settings if you wish to use the Face ID or Fingerprint ID option to reopen the app.
To learn more about setting biometrics, please view the video HERE
