Async Storage

React Native AsyncStorage is unencrypted.

Do not use AsyncStorage for sensitive data. Use expo-secure-store instead.

import AsyncStorage from '@react-native-async-storage/async-storage';

await AsyncStorage.setItem(
  storageKeyName,
  JSON.stringify(data)
);

await AsyncStorage.getItem(storageKeyName);

await AsyncStorage.removeItem(storageKeyName)

Expo Secure Store

Encrypted store. Does not support web/browser so you need to continue to use AsyncStorage for web.

async function add(key: string, value: any) {
  try {
    if (Platform.OS === 'web') {
      await AsyncStorage.setItem(key, value);
    } else {
      await SecureStore.setItemAsync(key, value.toString());
    }
  } catch (error) {
    console.error("Error saving data:", error); 
  }
}
