# Opting into Default User Required

> Opting into Default User Required

To opt into the simplified user model, you need to add \<AdvancedUserMode> to your
microsoftgame.config and specify "false" as shown below.

```xml theme={null}
<Game configVersion="1">
   <Identity Name="Sample" Publisher="CN=NoPublisher"/>
   <!-- much content removed -->
   <MSAAppId>PleaseChangeMe</MSAAppId>
   <TitleId>FFFFFFFF</TitleId>

   <!-- opt into requiring a default user at launch -->
   <AdvancedUserModel>false</AdvancedUserModel>
</Game>
```

Starting with the June 2022 GDK, all games opting into using the simplified
user model must also make sure that their microsoftgame.config has the following:

* configVersion equal to 1
* Specifies a title ID
* Specifies an MSA App ID

Please use the [MicrosoftGame.config Editor](/build/core-features/common/game-config/MicrosoftGameConfig-Editor) "Associate
with Store" feature to automatically retrieve these IDs from Partner Center.

In a future release of the GDK, the simplified user model will be the default.
At that future point, you will need to opt into the advanced user model where
this is no such guarantee that you have a default user at launch.
