How can I securely store authentication tokens in React Native?

How can I securely store authentication tokens in React Native?

You can use libraries like @react-native-async-storage/async-storage or react-native-keychain for secure storage.

What are the differences between AsyncStorage and Keychain?

AsyncStorage is simpler and suitable for less sensitive data, while Keychain provides more security for sensitive information.

Can you show me a code example using react-native-keychain?

Sure! Here's a basic example:

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

async function storeToken(token) {
  await Keychain.setGenericPassword('user', token);
}

async function getToken() {
  const credentials = await Keychain.getGenericPassword();
  return credentials ? credentials.password : null;
}

Is it safe to store tokens in AsyncStorage?

It's not recommended for sensitive tokens, as AsyncStorage is not encrypted. Use Keychain for better security.
