For game developers, a smooth, reliable player onboarding experience is essential to driving day-one retention and long-term engagement. Yet for years, developers looking to integrate Google authentication into Unity games often relied on deprecated sample bridges that struggled with modern Gradle build pipelines and AndroidX requirements. Today, we are thrilled to announce the launch of the Sign in with Google Mobile Plugin for Unity, now open-source and publicly available on [GitHub.](https://github.com/googlesamples/siwg-mobile-unity-plugin) Built specifically with modern engine requirements in mind---including full compatibility with Unity 6.5---this production-ready plugin replaces the legacy implementation with a first-party, high-performance authentication bridge. ### Key Highlights for Game Developers - Streamlined Native Performance: By implementing lightweight, native-only bridges, the plugin minimizes runtime overhead, removes legacy baggage, and ensures predictable, responsive sign-in interactions across devices. - Modern Security Standards: Integrates directly with Android's modern Credential Manager (Kotlin) and iOS's GIDSignIn (Objective-C++), giving players a fast, passwordless login experience while ensuring compliance with platform-level privacy and security standards. - Editor-Integrated Configuration: Developers can configure their Web Client ID and iOS Reversed Client ID directly inside the engine editor via Window \> Google Sign-In Native \> Settings---eliminating messy manual manifest edits. - Decoupled \& Backend-Agnostic: Rather than locking developers into a single backend stack, the plugin retrieves a signed Google ID Token (idToken) directly into your C# scripts via event callbacks. You can seamlessly hand off tokens to various Back end as a Service platforms, such as Firebase Authentication, Supabase, Auth0, etc... , or your own user management platform . - Frictionless Setup: Integrate the plugin easily by downloading the pre-built .unitypackage Whether you are an indie game developer prototyping your first title or an established studio optimizing player onboarding for your next global launch on Unity 6.5, getting started takes just minutes: 👉 Explore the Sign in with Google Plugin for Unity on the [GitHub repository](https://github.com/googlesamples/siwg-mobile-unity-plugin) Written by: - ## [Michelle Martin](https://developer.android.com/blog/authors/michelle-martin.md.txt) ###### Sr. Solutions Consultant, Users and Products [read_more View profile](https://developer.android.com/blog/authors/michelle-martin) ![View Michelle Martin's profile](https://developer.android.com/static/blog/assets/unnamed_29_8358471ffe_MSkhy.webp) ![View Michelle Martin's profile](https://developer.android.com/static/blog/assets/unnamed_29_8358471ffe_MSkhy.webp) Continue reading - [![View Amy Zeppenfeld's profile](https://developer.android.com/static/blog/assets/Amyzeppenfeld_50a8b9e7f8_Z17af4b.webp)](https://developer.android.com/blog/authors/amy-zeppenfeld.md.txt)[![View Vinny DaSilva's profile](https://developer.android.com/static/blog/assets/unnamed_5_cdab7ecfba_Z1iwWr5.webp)](https://developer.android.com/blog/authors/vinny-da-silva.md.txt) 06 Nov 2026 06 Nov 2026 ![](https://developer.android.com/static/blog/assets/ABL_149_Strapi_A2_B_8fa837edce_1zewyL.webp) [Product News](https://developer.android.com/blog/categories/product-news.md.txt) ## [Build for an expanding lineup of Android XR devices with production-ready tools from Android Developer Summit](https://developer.android.com/blog/posts/build-android-xr-devices-tools.md.txt) [arrow_forward](https://developer.android.com/blog/posts/build-android-xr-devices-tools.md.txt) From full immersion at home to glanceable experiences on the go, building on Android XR lets you meet users at any moment across the entire spectrum of spatial applications.
