Is React Native's Async Storage secure?

Question

I want to store sensitive data locally in a React Native app.

Is the data only available to the app that wrote it?

Answer 1

For very sensitive app or user data, you could try something like https://github.com/oblador/react-native-keychain on iOS(uses iOS Keychain) or https://github.com/classapp/react-native-sensitive-info for both Android and iOS(uses Android Shared Preference and iOS Keychain).

Both of them come with very fluent API and straightforward way of linking with react-native link and are a more secure way of preserving data you want to keep away from prying eyes.
