Compare B2B identity tradeoffs: SAML SSO, SCIM, organizations, MFA, audit logs, pricing model, and implementation complexity.

Consider Firebase Auth for B2C-first products that want a fast managed baseline.

Watch out: It is not the default choice for deep B2B SSO and SCIM requirements.

Choose Firebase Auth when the specific deployment, B2B, cost, or developer-experience tradeoff above is more important.
