Company information
The facts on file
- Description
- Firebase Authentication is Google's managed identity service providing backend services, SDKs and ready-made UI libraries for email/password, phone, anonymous and federated sign-in (Google, Apple, X, Facebook, GitHub) across iOS, Android, web, C++ and Unity. It shares billing and backend with Google Cloud Identity Platform, which adds enterprise SAML/OIDC federation. It targets mobile and web app teams — particularly those already on Firestore, Cloud Functions or Firebase Hosting — that need standard consumer sign-in shipped quickly.

- App Hosting & PaaS
- Products

With Identity Platform: 50,000 MAUs free and 50 SAML/OIDC MAUs free. pricing page ↗
- Regulatory
- Billing runs through Google Cloud and the Blaze plan requires a Cloud billing account. Non-USD customers are billed at Google Cloud Platform SKU list rates rather than a converted USD price. FirebaseUI is open source while the backend service is proprietary and hosted. No compliance certifications, data-residency commitments or SLA figures were found on the pages retrieved this session — regulated buyers must confirm in the Google Cloud compliance centre that Firebase Authentication specifically is in scope.
