Multi-tenancy on GCP is configured through Identity Platform, allowing each tenant to maintain distinct authentication environments and custom identity providers. This enables B2B SaaS applications to isolate user pools while sharing underlying infrastructure securely.

SAML and OIDC federation are fully supported for enterprise authentication in Google Cloud Identity Platform. You can configure these protocols to enable single sign-on, allowing users to authenticate through corporate identity providers seamlessly.

Implementing multi-factor authentication is best handled via Identity Platform configurations, which support MFA integration for web and mobile applications. This adds a critical layer of security beyond primary sign-in methods like email or social logins.

GCP Identity Platform supports custom logic during user sign-in through blocking functions. These functions intercept the authentication process to apply custom validation rules or modify user attributes before granting access.

Social logins like Google and Facebook are configured directly within Identity Platform to authenticate users quickly. This streamlines the sign-in experience for web and mobile applications without requiring custom password management.

Server-side integration patterns for Identity Platform are needed when handling enterprise-grade security and scalability requirements. They enable secure token verification and session management for backend services supporting web and mobile clients.
