Auth patterns

The B2B-ready auth surface — single sign-on, roles, and multi-tenant boundaries — in place as a pattern before feature work begins.

The problem

Enterprise buyers ask about auth first.

One of the first questions an enterprise buyer asks is how sign-on, roles, and tenancy work. Auth is custom for nearly every application, and it's the surface a deal interrogates hardest — SSO, SAML, MFA, and clean data boundaries between organizations.

Blueprint has that surface in place from the start, so it's ready when the conversation turns to it, not a scramble afterward.

How it works

Sign-on, roles, and tenancy, wired in as a pattern.

Auth is wired in at scaffold time. The frontend uses a managed identity provider's components for sign-in and account management; the backend validates the session on every request and surfaces organization, role, plan, and entitlements, isolating each tenant's data by organization.

Single sign-on, SAML, and MFA are configuration, not new application code — and the entitlement checks a product needs for plan-based gating are already carried in the session.

  • Single sign-on, SAML, and MFA available without changes to application code
  • Role-based access enforced in the backend on every request
  • Multi-tenant isolation — each organization's data stays its own
  • Plan and entitlement checks carried in the session, ready for gating
  • Test fixtures for deterministic end-to-end auth flows

B2B-ready auth from the first commit.

The first enterprise deal shouldn't be the moment your auth layer gets rewritten. Blueprint has that surface in place from the start.
