Firebase Authentication API
Google Firebase's authentication service supporting email/password, phone, and social logins (Google, Apple, GitHub, etc.) with a backend Admin SDK for user management and token verification.
Best When
You're already in the Firebase/GCP ecosystem and need simple multi-provider auth without enterprise features.
Avoid When
You need SAML SSO, complex RBAC, or want to avoid vendor lock-in with Google.
Use Cases
- • Adding multi-provider auth to mobile or web apps quickly
- • Verifying Firebase ID tokens on the backend via Admin SDK
- • Managing users programmatically (create, disable, delete) via Admin SDK
- • Custom token generation for server-side authentication flows
- • Linking multiple auth providers to a single user account
Not For
- • Enterprise SSO/SAML (use Auth0, WorkOS, or Okta instead)
- • Complex authorization/RBAC beyond basic user management
- • Teams avoiding Google/GCP dependency
