React Native AsyncStorage is a simple key-value storage system that saves data as plain text. This means that anyone with access to the device or its backups can potentially read your auth tokens, API keys, or other sensitive data if you use AsyncStorage.
Storing sensitive data unencrypted can also violate Google Play and AppStore guidelines which might result in your app being rejected. Reviewers might run basic security tests that could expose unencrypted token storage.
SecureStore is Expo's abstraction layer that leverages the native security infrastructure of both iOS and Android platforms. SecureStore automatically encrypts all data before storage and provides a unified API that works identically on both iOS and Android. While SecureStore has slightly more overhead due to encryption/decryption operations, the performance impact is negligible for typical use cases like token storage. The security benefits far outweigh any minor performance considerations.
