OAuth2 Platform

Standards-based identity with OAuth 2.1 & OpenID Connect—built around Duende IdentityServer and BFF (Backend-for-Frontend) for reduced risk and a great UX.

Security First

Adopt OAuth2/OIDC with PKCE, short-lived tokens, and hardened flows. Reduce bespoke code, shrink attack surface, and align to zero-trust principles.

Built to Scale

Centralize identity with Duende IdentityServer, manage clients & APIs consistently, and keep operations observable with logs, metrics, and audits.

Frictionless UX

BFF keeps tokens off the browser. Add Passwordless (FIDO2/WebAuthn) for fast, phish-resistant sign-ins that users actually prefer.

Backend-for-Frontend (BFF)

The BFF mediates between UI and APIs—handling cookies, tokens, and CSRF defenses on the server. Your SPA or MVC app never stores access tokens in the browser, lowering exposure to XSS and token theft.

  • No tokens in local/session storage
  • HttpOnly/SameSite cookies with short lifetimes
  • CSRF protection and origin checks by default
  • Clear separation of UI concerns vs server auth

Typical BFF flow
  1. Browser → BFF: UI calls same-origin endpoints.
  2. BFF ↔ IdentityServer: OIDC login with PKCE; session established.
  3. BFF → APIs: Server exchanges/refreshes tokens securely.
  4. API responses return to UI—no tokens in the browser.
  5. Logout ends session & revokes tokens centrally.

Platform Features

Everything you need to run secure, standards-based identity with governance and great DX.

Fine-Grained Access

Scopes, roles, and claims shaped to your domain model.

  • Multi-tenant & org boundaries
  • API-level policy enforcement
Observability & Auditing

Trace sign-ins, consents, and token events with confidence.

Reference Architecture

A modular identity layer: IdentityServer for issuance, a BFF for client mediation, and API gateways enforcing scopes and policies. Add passwordless to reduce friction and risk.

  • Zero-trust aligned segmentation
  • Short-lived tokens & DP signatures
  • Telemetry for audits & incident response

FAQ

PKCE protects the authorization code exchange—but doesn’t address where tokens live. BFF keeps tokens server-side, which mitigates theft via XSS and lowers client complexity.

Yes. We layer FIDO2/WebAuthn alongside your current factors and roll out progressively, keeping UX smooth while raising assurance levels.

Tenants can map to issuers, clients, and scopes. We enforce boundaries at issuance time and in downstream APIs with policy and claims shaping.
