Save sensitive data in React Native

Question

I am building a React Native application and I need to save some sensitive data like a token and a refresh token. The obvious solution is to save that information using Asyn

Answer 1

I really recommand you to use a library like react-native-keychain to store private data in react-native

For Android API level:

• 16-22 use Facebook Conceal
• 23+ use Android Keystore

You can use it like that:

// Generic Password, service argument optional
Keychain
  .setGenericPassword(username, password)
  .then(function() {
    console.log('Credentials saved successfully!');
  });

// service argument optional
Keychain
  .getGenericPassword()
  .then(function(credentials) {
    console.log('Credentials successfully loaded for user ' + credentials.username);
  }).catch(function(error) {
    console.log('Keychain couldn\'t be accessed! Maybe no value set?', error);
  });
