Simple Sign-In with Google

Simple Sign-In with Google 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 other platforms? ● Simple Sign-In with Google ● Simple Sign-In with Apple ● Simple Sign-In with Facebook ● Simple Sign-In with X (Twitter) ● Simple Sign-In with Telegram ● Simple Sign-In with Microsoft ● Simple Sign-In with TikTok 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 visit our GitHub for known issues.
