[PAID BOUNTY - $660] Note Locking - Biometrics/PIN

Description

## Bounty Overview Build note-level locking for the warpSpeed Notes experience using biometrics, device authentication, or a user-defined PIN. This bounty gives users a private vault inside Notes. Users should be able to lock new or existing notes, clearly see which notes are locked, and unlock them only after successful authentication. Locked notes must stay hidden or obscured until unlocked, and the app should require re-authentication after app restart or after a configurable timeout. This bounty is part of the warpSpeed OPEN developer bounty programme. ## Reward $660 ## Difficulty Medium ## Main Skills * React Native * TypeScript * Biometric Authentication * Secure UI States * Notes Feature Development * Mobile Security UX * Reusable Component Architecture ## Design Reference https://xd.adobe.com/view/b74cd4eb-ec51-400e-bdb2-5041a123510c-e21f/ ## High-Level Scope The selected developer will build a secure note locking feature for the Notes experience.
