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

Use Lobby and Matchmaker with Authentication

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 that can’t be manipulated by anyone else.

Unlock cross-play friendly communication

Introducing Unity Player Accounts

Player Accounts is our Unity-branded player sign-in solution. It offers your players a secure, consistent, and seamless account experience. For example, Player Accounts has single sign-on (SSO) support so players can log in once and access all Player Accounts enabled games without reentering credentials.

Key benefits
Flexible

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

If you have an existing identity solution, you can easily integrate your custom authentication system through our BYOI support.

Seamless

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

Extensible

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