This page explains how to set up biometric authentication.
* Available only on smartphones that support fingerprint or face recognition.
①Tap the menu button "≡" at the top left, then select Settings.
②Tap the "Biometric Authentication" button in app settings.
③If the "Biometric Authentication" button is orange (on), setup is complete.
When you finish using the app, swipe it closed instead of using Log Out. The biometric authentication screen will appear the next time you open the app.
(If you swipe the app closed, you are also logged out automatically.)
How to close (quit) the app differs by device. See the pages below.
