SOLUTION
Zero‑Token SPAs
Eliminate token theft Policy on every call Audit‑ready proof
How it works
- Edge calls BFF for ForwardAuth; SPA never sees tokens.
- BFF validates session and requests PDP decision per route.
- On allow, BFF brokers tokens and applies constraints (caps, egress, params).
- Signed receipts capture policy snapshots and usage.
Standards
- OIDC + OAuth 2.0 (Auth Code + PKCE)
- OpenID AuthZEN decisions at the BFF
- DPoP and RFC 8693 Token Exchange (optional)
