How can i implement feature like remember me when authenticating via react application? I think unencrypted AsyncStorage isn't the best way to do it, because data is open for users. I've tried to use realm, but stuck into problem that cannot be resolved in android using expo to test application. It says that i need to pile native code for android and edit that (Add realm object creation in MainApplication.js). I don't want to pile my project while it's not released yet. How does instagram and the other RN-apps store authentication data? What is the best approach?

What is the best way to store private data in react-native?

I would remend using a library like react-native-keychain to store private data in react-native

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);
  });
