## Setup OIDC Authentication with Google Provider 

To use Google Sign In, you will need to create a project on the [Google Developer Console](https://console.developers.google.com) and create an OAuth 2.0 client ID. 

1. Get an app set up on the Google Developer Console 
2. Go to the Credentials Page Create an app for your project if you haven't already. 
3. Once that's done, click "Create Credentials" and then "OAuth client ID." You will be prompted to set the product name on the consent screen, go ahead and do that.

**After updating  .env file, you have trigger code rebuild by modifying this file /screens/SocialLogin/behaviors.js. Just add a new line or any change and save it then relaunch the app.**

### Connect to your Expo account

When using Expo services like AuthSession, you should use `expo start` and login to your Expo.io account because`react-native-scripts start` uses a logged-out, anonymous developer account that's why you will have a warning message ***You are not currently signed in you Expo on your development machine.***
