Google Login Plugin

To use Google login in Unreal Engine, you need to install a Google Sign-In plugin or integrate native SDK.

• Android: Google Play Games Services
• iOS: Google Sign-In SDK

ID Token Issuance

You must obtain an ID token through Google OAuth login. Pass this token as the linked_id parameter.
