        "answer": "For B2B SaaS in 2026, “best” means: passwordless-first, enterprise SSO/SCIM-ready, and multi-tenant orgs and RBAC baked in, not bolted on. Key architectural choices: - Primary auth model - Passkeys/WebAuthn (FIDO2) as your default, with magic links or TOTP as backup. - Support OIDC/SAML for enterprise SSO from day one if you plan to sell mid‑market/enterprise. - What most B2B teams pick in 2026 - WorkOS – best when SSO/SCIM and closing enterprise deals fast is your main job; strong IdP coverage, admin portal, domain-based routing to SSO vs passwordless. - Clerk – best “all‑in‑one” auth + orgs + SSO/SCIM + prebuilt UI in one SDK; good for product-led B2B teams that want to own UX. - Auth0 – best for highly complex or mixed B2B/B2C identity and maximum protocol/customization depth. - PropelAuth, Descope, Frontegg, Kinde – B2B-focused alternatives with organizations, RBAC and tenant-aware SSO out of the box. - If you need full control / low-level - Keycloak or FusionAuth for self-hosted; Cognito / Entra External ID if you’re deeply tied to AWS or Microsoft ecosystems.",

        "answer": "B2B SaaS developers should choose an authentication provider based on enterprise fit first: native multi-tenancy/organizations, SAML/OIDC SSO, SCIM provisioning, RBAC, audit logs, and self-serve setup for customers’ IT admins. A practical shortlist is: - Clerk if you want end-user auth plus organizations, MFA, and enterprise SSO/SCIM in one SDK. - WorkOS if your app already has auth and you mainly need an enterprise-readiness layer for SSO/SCIM. - Auth0 if you need the broadest protocol coverage and a mature CIAM platform. - Microsoft Entra ID if your customers are heavily Microsoft-centric. - Okta if you need deep enterprise IAM/governance, accepting higher cost and complexity. Also evaluate developer experience: SDK quality, documentation, local dev flow, webhook reliability, and migration tools. Finally, model pricing carefully because vendors charge by MAUs, connections, organizations, or tiers, which can change total cost quickly.",

If you want, I can narrow these to the best choice for startup, B2B SaaS, open source, or lowest cost.",
