Google Authentication and Google Play Games Authentication Separated

To comply with the Google Play Games Guide for PC and to accommodate Google’s next-generation Play ID, Google authentication and Google Play Games authentication were separated (implemented in SDKv4.21.0).
Only titles that were registered in the App Center prior to Jun 7th, 2023 are impacted; new registrations are not.

Common Modifications

It was necessary to change the login IdP settings of the App Center and add legacy support settings due to the separation of Google authentication and Google Play Games authentication. In SDKv4.21.0, ‘Sign in with Google Play’ operates as an implicit login when legacy support is marked as ‘Disabled’.

Legacy Support Added
  • It was necessary to change the login IdP settings of the App Center and add legacy support settings due to the separation of Google authentication and Google Play Games authentication. In SDKv4.21.0, ‘Sign in with Google Play’ operates as an implicit login when legacy support is marked as ‘Disabled’.
    The legacy support can be checked at the App Center menu.

    • Menu Location: Hive Console > App Center > Game Management > Game List > Hive Product Settings > Legacy Support [Check]
  • Login IdP Settings Changed
  • In the App Center, ‘Sign in with Google’ and ‘Sign in with Google Play’ are separated from ‘Sign in with Google/Google Play’ set in the signin tab for each App ID.
  • The current game app ID login setting has been changed from ‘Sign in with Google/Google Play’ to ‘Sign in with Google’. If the legacy support is marked as ‘Enabled,’ even if the login setting is changed, the icon exposed to the IdP during explicit login remains as ‘Sign in with Google Play,’ matching the sync status within the in-game profile.
  • When registering ‘Sign in with Google Play,’ you must register the Client ID and Client Secret in the App Center. Register the Redirect URI in the Google Console.
    The login settings can be checked at the App Center menu below.

    • Menu Location: Hive Console > App Center > Manage AppID > List of AppIDs > Login [Check]

    Games Using Google Play Games for PC

    The following modifications must be made to games that were registered before Jun. 7th, 2023 and use or intend to use Google Play Games (GPG) for PC.

  • Google Play Games for PC explains that “Your game should be automatically saved with your Play Games Services ID without requiring you to select any buttons. Gameplay should be activated without the need to manually log in to any account.”

    • You must update the SDK version to v4.21.0 and change legacy support from “Enabled” to “Disabled.”
    • In the login settings of the App Center, you must select both ‘Sign in with Google’ and ‘Sign in with Google Play’. In addition, the game must show ‘Google sync’ and ‘Google Play sync’ as IdP sync in the in-game profile.
    • If the ‘Sign in with Google’ button is set in the App Center login settings, the explicit login button will change from ‘Sign in with Google Play’ to ‘Sign in with Google’ when legacy support is changed from ‘Enabled’ to ‘Disabled’. Change the App Center settings while the game is being updated to avoid user confusion.
    • The Implicit Sign-in changes from ‘Sign in with Google’ to ‘Sign in with Google Play’ when Legacy Support is changed from ‘Enabled’ to ‘Disabled’.
    • For existing logged in users, Google authentication and Google Play authentication are separated, so the IdP sync must be displayed for both Google sync and Google Play sync in the in-game profile.
    • As Google authentication and Google Play authentication have been separated, new users who select ‘Sign in with Google Play’ when signing in with Google in Crossplay will create a new account.
