Identity Platform and Firebase Authentication offer similar functionality. Both allow you to easily sign users in to your apps by providing backend services, SDKs, and UI libraries. However, Identity Platform offers additional capabilities designed for enterprise customers, such as:
- OIDC and SAML authentication.
- Multi-tenancy support.
- Identity-Aware Proxy integration.
- BAA coverage.
- A 99.95% uptime SLA.
Identity Platform is fully compatible with both Google Cloud and Firebase products. If you are currently using Firebase Authentication and you upgrade to Identity Platform, your app will continue to work with existing Firebase services.
