# PlayFabMultiplayer.Initialize method

Initializes an instance of the PlayFab Multiplayer library.

```csharp theme={null}
public static void Initialize()
```

## Remarks

Initialize() cannot be called again without a subsequent [`Uninitialize`](/services/playfab/multiplayer/lobby/unity-multiplayer-api-reference/PlayFab.Multiplayer/PlayFabMultiplayer/Uninitialize) call.

Every call to Initialize() should have a corresponding Uninitialize() call.

The playFabTitleId is read from PlayFab's static PlayFabSettings asset. It can be changed Using Unity menu, PlayFab | MakePlayFabSharedSettings menu. It must be the same PlayFab Title ID used to acquire the PlayFab Entity Keys and Entity Tokens that will be passed to [`SetEntityToken`](/services/playfab/multiplayer/lobby/unity-multiplayer-api-reference/PlayFab.Multiplayer/PlayFabMultiplayer/SetEntityToken).
