This sample demonstrates a simple PlayFab sign-in flow for Unity. Players can log in with an email and password, create a new account, or continue as a guest. Credentials can optionally be remembered across sessions.

​
Requirements

Unity 2018.3+

The project was created with Unity 2018.3 and requires that version or later.

Visual Studio 2017+

Visual Studio 2017 (Update 15.7) or later is required to open and build the project.

Android / iOS device

A physical or virtual Android/iOS device provides the best experience.

PlayFab title ID

A valid PlayFab Title ID must be configured before running the sample.

​
PlayFab configuration

Before running the sample you must supply your PlayFab Title ID. You can do this in one of two ways:
  • Use the PlayFab Editor Extensions for Unity, or
  • Open Assets/PlayFabSdk/Shared/Public/Resources/PlayFabSharedSettings.asset in the Unity Inspector and set the Title ID field directly.

​
Setup

1

Clone the repository

git clone https://github.com/Myst0gan1/PlayFab-Samples.git
2

Open the project in Unity

In Unity Hub, click Open and navigate to:
PlayFab-Samples/Samples/Unity/PlayFabSignIn
3

Configure your Title ID

Either use the PlayFab Editor Extensions panel, or set the Title ID directly in Assets/PlayFabSdk/Shared/Public/Resources/PlayFabSharedSettings.asset.
4

Open the sample scene

In the Project window, open the scene located in Assets/Scenes/.
5

Enter Play mode

Press Play in the Unity Editor. A sign-in dialog appears. Use an existing account, create a new one, or sign in as a guest.

​
Using the sample

After launch you are prompted to sign in. The available options are:
  • Email / password login — authenticate with an existing PlayFab account.
  • Create account — register a new account with an email and password.
  • Guest login — sign in anonymously without credentials.
  • Remember me — persist sign-in info so the dialog is skipped on the next run.
Once signed in, you can clear sign-in data or the remembered session from the post-login screen.

​
Code structure

All scripts live in Assets/Scripts/, split into two sub-folders:
FileResponsibility
PlayFabAuthService.csEncapsulates all PlayFab authentication calls: anonymous login, email/password login, account registration, and session-token persistence.
FileResponsibility
LoginWindowView.csDrives the sign-in dialog, binds UI events to PlayFabAuthService, and manages the “remember me” toggle state.

​
Key PlayFab features

LoginWithEmailAddress

Authenticates a returning player using their email and password.

RegisterPlayFabUser

Creates a new account with email, password, and optional display name.

LoginWithCustomID

Provides anonymous guest login via a device-generated custom ID.

Session persistence

Saves the session ticket locally so players are not prompted again on subsequent runs.
