Knowing the identity of a player allows you to provide a variety of features and services to both game developers and players to ensure security, consistency, and safety with every interaction. Unity Authentication provides anonymous and platform-specific authentication solutions for supported platforms, including mobile and PC. Anonymous access doesn’t require the player to enter sign-in credentials or create a player profile, but access through a platform requires sign-in credentials. Unity provides authentication an API call, enabling game developers to focus on doing what they do best - creating games.

When a returning or new player logs into your game, Unity Authentication generates session and authentication tokens and a player ID, these enable a means to identify a player and store player game data (for example, saving game state and recording in-app purchases), a consistent game experiences to the player (for example, points for leader boards and suggested in-app purchases), insight about the player’s game behavior across multiple devices and multiplayer features on various platforms.
