This project is the completed app for the following Auth0 Developer Blog articles:

• Get Started with Auth0 Authentication in React Native Android Apps
• Get Started with Auth0 Authentication in React Native iOS Apps

These articles walk the reader through the process of adding Auth0 authentication to Android and iOS apps build using React Native.

The resulting app has these screens:

1. The Login screen, which the user will see when the app launches. It has a Login With Auth0 button that takes the user to the Universal Login screen when pressed.
2. The Universal Login screen, where the user authenticates themself — that is, where they enter their user name and password or perform some other action to prove their identity. You don’t have to code this screen; a call to the Auth0 API brings it up. After logging in, the app takes the user to the Loading screen.
3. The Loading screen displays an activity indicator while the app determines the user’s login status. In many cases, the user won’t even see this screen.
4. The Account screen, where the user goes if they log in successfully. It displays a picture of the user and the user’s name and a Logout button that takes them to the Login screen when pressed.

The Android version’s screens look like this:

The iOS version’s screens look like this:
