Authenticate your players for a seamless user experience with either anonymous or platform-specific sign-in solutions.

Keep up with players across multiple devices

With so many apps working across multiple devices, you never know if a player will be logging in from their mobile, laptop, or tablet to play. 

By using Cloud Save with Unity Authentication, you can enable players to sign in with various platform accounts, and make sure their progress is saved across their devices.

Form parties and lobbies in your multiplayer game

When creating a multiplayer game, you need to ensure your players can connect, socialize, and play together safely and enjoyably.

Use Lobby and Matchmaker with Authentication to allow your players to securely authenticate, connect, and communicate with each other with confidence.

Economy and Authentification

Protect your game economy

Create a strong and secure game economy using Economy and IAP with Authentication. Set up authenticated sign-in in your game to associate unique tokens and an ID for each player which can’t be manipulated by anyone else.

Key benefits


Enable new users to create accounts in your game through multiple supported platforms, including Google Play Games, Apple, Facebook, and Steam.


Anonymous sign-in creates a new user for a game session without any input from the player and is a quick way to get started with your game.


Unity Authentication easily integrates with multiple Unity Gaming Services products, including Analytics, Cloud Code, Cloud Save, Economy, Lobby, Matchmaker, Relay, Remote Config, and Vivox.
