What are some secure storage libraries for React Native?

There are several secure storage libraries for React Native, including:

1. @react-native-async-storage/async-storage - A simple, unencrypted, asynchronous, persistent, key-value storage system.
2. react-native-keychain - Provides secure storage for sensitive data using the device's secure storage mechanisms.
3. react-native-sensitive-info - A library for storing sensitive information securely, using the Keychain on iOS and SharedPreferences on Android.

How do I implement react-native-keychain?

To implement react-native-keychain, follow these steps:

1. Install the library using npm or yarn:

   npm install react-native-keychain
   

2. Link the library (if using React Native < 0.60):

   react-native link react-native-keychain
   

3. Import the library in your component:

   import * as Keychain from 'react-native-keychain';
   

4. Use the setGenericPassword and getGenericPassword methods to store and retrieve credentials.

Is react-native-sensitive-info better than react-native-keychain?

It depends on your use case. react-native-keychain is great for secure storage of credentials, while react-native-sensitive-info is more versatile for storing various types of sensitive data. If you need to store passwords, keychain is often preferred due to its integration with the device's secure storage.

Can I use these libraries for both iOS and Android?

Yes, both react-native-keychain and react-native-sensitive-info are designed to work on both iOS and Android, providing a consistent API for secure storage across platforms.
