From 4ffbee31e59aac8b03e783c34f4b3802c2da89b0 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Sun, 19 Apr 2026 20:23:27 +0000 Subject: [PATCH] [jules] enhance: Add Biometric Authentication option (FaceID/TouchID) for mobile Implemented biometric authentication for the mobile application to allow users to securely and quickly log in using FaceID or TouchID. - Integrated `expo-local-authentication` to support native biometric hardware. - Updated `mobile/context/AuthContext.js` to handle `isBiometricEnabled` state, securely maintain credentials when logging out/restarting, and prompt the user gracefully. - Added a "Enable Biometric Login" toggle switch in `mobile/screens/AccountScreen.js`. - Added a "Login with FaceID / TouchID" button to `mobile/screens/LoginScreen.js` for returning users with enabled biometrics. - Updated `.Jules/todo.md` and `.Jules/changelog.md` to reflect the completion of this task.
