Best For
Rapid prototyping and Google-native stacks; low-friction auth for AI apps that don't need agent-specific authorization
Enterprise SSO, M2M authentication, and fine-grained authorization for B2B agent products
Limitations
No token delegation, no FGA, no agent SDK; vendor lock-in to Google Cloud; limited authorization model
No dedicated agent SDK; FGA is strong but relatively new; async authz patterns require custom integration
Supported Not supported Unverified
