This feature authenticates players using a specific identifier or third-party service, registering a session upon login. Authentication is essential for managing player sessions and unlocking access to all other LootLocker features. LootLocker offers three types of authentication: Guest Login, Platform Login, and White Label Login. Choosing the right option depends on your game’s requirements and target platforms. ### Guest Login Guest Login assigns each player a unique ID, providing quick and seamless access. Commonly used in web or mobile games, this method prioritizes fast entry without the need for a traditional login. However, since the unique player ID is not tied to a username and password, it’s not intended for games that require secure identity verification. ### Platform Login Platform Login supports authentication through First Party Platforms such as Steam, Xbox, and Apple. This method uses the player’s Platform ID to register their session, making it ideal for games integrated with established platform ecosystems. ### White Label Login White Label Login provides a custom username and password setup, allowing players to create personal accounts directly within your game. This method offers more control over player account management, making it suitable for games that require a standalone authentication system. {% hint style="info" %} If you’re considering cross-platform support, explore [Unified Player Accounts](/players/unified-player-accounts.md) to enable players to link multiple authentication methods, ensuring seamless cross-platform experiences. {% endhint %} ### Use Cases * Cross-platform accounts * Username / Password login * Simple login for mobile & web games ### How-to (Authenticate With) * [Guest Login](/players/authentication/how-to/guest-login.md) * [Sign in with Apple](/players/authentication/how-to/sign-in-with-apple.md) * [Apple Game Center](/players/authentication/how-to/apple-game-center.md) * [Sign in with Google](/players/authentication/how-to/sign-in-with-google.md) * [Google Play Games](/players/authentication/how-to/google-play-games.md) * [Steam](/players/authentication/how-to/steam.md) * [PlayStation](/players/authentication/how-to/playstation.md) * [Xbox](/players/authentication/how-to/xbox.md) * [Nintendo Switch](/players/authentication/how-to/nintendo-switch.md) * [Epic Games Store](/players/authentication/how-to/sign-in-with-epic-games.md) * [Meta / Oculus](/players/authentication/how-to/meta.md) * [White Label Login](/players/white-label-login/how-to/white-label-login.md) --- # Agent Instructions This documentation is published with GitBook.
