Overview

Simple Google Sign-In provides Google sign-in with OAuth 2.0 for Android, iOS, Windows, Mac, Universal Windows Platform (UWP) and WebGL apps made with Unity.

Any doubts? Try it in real apps!
Need sign-in for Facebook? Try my another asset Simple Facebook Sign-In.

Authentication may be a headache, especially for beginners, especially on different platforms. So I decided to take a fresh look of current possibilities that Google and Unity provide at the moment. And after a week of research I said "Bingo!". My asset is an extremely simple solution with about 200 lines of code only. Lightweight, tiny and clean, with no massive plugins and 3rd party libs!

Benefits
● Cross-platform user auth for cross-platform games and apps
● No plugins, not 3rd party libs, no dependencies
● No impact to build size
● Get access tokens for integration with other Google services
● More security for client-server apps (get access tokens on a client, get all user data on a server to avoid tampering)
● JSON Web Tokens (JWT) validation
● SFSafariViewController is used on iOS (required by App Store review)
● Deep linking for Windows (UNITY_STANDALONE_WIN)

Setup steps
Please visit our GitHub for setup instructions.

Generic workflow (for platforms that support deep linking)
● Your app navigates users to Google using a default web browser
● Users perform sign-in to their Google account
● Google redirects users to your app (using deep linking when possible) and provides an authorization code in URI parameters
● The app is activated and obtains an authorization code
● The app exchanges the code for an access token
● The app requests user data with the access token (ID, name, email and other data according access scope defined)

Loopback flow for Editor and Windows (optional)
● Google redirects users to http://localhost:PORT/
● The app listens to localhost using HttpListener

Middlware flow for WebGL
● Redirect to Authorization Middleware is used to temporary save an auth code
● The app obtains the code from Authorization Middleware with a POST request

Known issues
● Please refer to the section on GitHub
