Run `deno task setup` (generates `infra/stack.env` with cryptographically + secure random secrets). + 2. Run `docker compose -f infra/compose.yml up -d`. + 3. Navigate to `https://auth.atyg.org/register` in your browser and register + your first WebAuthn passkey (touch your YubiKey / Touch ID). +- **Why it's painless:** + - The database schema (`users`, `apps`, `grants`, `passkeys`, `audit_ledger`) + auto-migrates idempotently on first boot. + - The first registered user automatically becomes the **Global Admin** + (`isGlobalAdmin`). You never have to manually run SQL scripts to bootstrap + admin access. + +--- + +### Use Case 2: Adding Auth to Tier 1 Off-the-Shelf Apps (Grafana, Portainer, PGAdmin, etc.) + +- **Difficulty Level:** **Minimal (Zero Code / 3 Docker Labels)** +- **What you actually have to do:** + - Add the Traefik ForwardAuth middleware label to your container's + `compose.yml`: + ```yaml + services: + grafana: + image: grafana/grafana:latest + labels: + - "traefik.enable=true" + - "traefik.http.routers.grafana.rule=Host(`grafana.atyg.org`)" + - "traefik.http.routers.grafana.middlewares=authyes-forwardauth@docker" + ``` +- **Why it's painless:** + - Traefik intercepts unauthenticated requests at the network edge in $<1$ms + before traffic reaches the container. + - Auth-Yes validates the wildcard session cookie and injects + `X-Forwarded-User: alice` downstream so Grafana automatically logs the user + into their profile. + +--- + +### Use Case 3: Adding Auth to Tier 2 Custom Web/SSR Apps (ed-droid, Hono, Next.js, Remix) + +- **Difficulty Level:** **Minimal (2 Lines of Code)** +- **What you actually have to do:** + - **Option A (Instant Ingress Hydration on first SSR byte):** + ```typescript + // Read the injected grant vector directly from the initial request: + const userId = req.headers["x-forwarded-user-id"]; + const scopes = req.headers["x-forwarded-scopes"]?.split(",") || []; + ``` + - **Option B (In-App SDK Route Guard with sub-30µs memory cache):** + ```typescript + import { authMiddleware, requireScope } from "@auth-yes/sdk/hono"; + + app.use("/admin/*", authMiddleware(authSdk), requireScope("admin")); + ``` +- **Why it's painless:** + - ForwardAuth injects pre-evaluated user identity and RBAC grants at the edge + for instant SSR UI hydration. + - In-app SDK verification leverages Valkey 8 RESP3 client tracking, validating + tokens in local RAM in $<30\mu s$ without database round-trips. + +--- + +### Use Case 4: Headless Edge Daemons & IoT Device Authentication + +- **Difficulty Level:** **Low (RFC 9421 HTTP Message Signatures)** +- **What you actually have to do:** + - Register the edge node's Ed25519 public key once via the admin API: + ```bash + curl -X POST https://auth.atyg.org/api/admin/hwk \ + -H "Cookie: session_id=..." \ + -d '{"jwk":{"kty":"OKP","crv":"Ed25519","x":"..."}, "name":"telemetry-drone-01"}' + ``` + - Edge devices send signed HTTP requests with `Signature-Input` and + `Signature` headers. +- **Why it's painless:** + - Eliminates fragile static API tokens and shared secrets. + - Signatures survive proxy TLS termination and are validated in $<5\mu s$ via + Valkey $O(1)$ fingerprint set checks (`SISMEMBER auth:hwk:fingerprints`). + +--- + +### Use Case 5: Zero-Touch Internal Microservice mTLS & SPIFFE Mesh + +- **Difficulty Level:** **Minimal (Zero Manual Certificate Management)** +- **What you actually have to do:** + - Internal backend daemons query the local SPIRE agent over a UNIX domain + socket via `spire_ffi`. + - The SDK automatically validates the client's SPIFFE ID (e.g. + `spiffe://atyg.org/ed-droid`) against the authorized application registry. +- **Why it's painless:** + - Native Rust FFI crate (`spire_ffi`) handles short-lived X.509 SVID rotation + in the background every 60 minutes. + - No manual PKI root management, zero CA expiration panics, and zero hardcoded + mTLS secrets. + +--- + +### Use Case 6: Live Telemetry & WebSockets (The Ghost Cockpit Protocol) + +- **Difficulty Level:** **Minimal (1 Middleware Guard in Hono)** +- **What you actually have to do:** + - Wrap your WebSocket endpoint with the session guard in `sdk/hono.ts`: + ```typescript + app.get( + "/ws/telemetry", + upgradeWebSocket((c) => { + const token = getCookie(c, "session_id"); + const guard = createWebSocketGuard(authSdk, token); + return { + ...guard.handlers, + onMessage(event, ws) { + // Process telemetry data stream + }, + }; + }), + ); + ``` +- **Why it's painless:** + - When a session expires or is revoked, the SDK sends + `{ "type": "AUTH_REVOKED", "reason": "SESSION_EXPIRED" }` and cleanly closes + the socket. + - The frontend freezes UI state in memory, triggers an ambient WebAuthn + prompt, and seamlessly resumes telemetry without refreshing the page or + losing user input. + +--- + +### Use Case 7: User Device Loss & Zero-Downgrade Self-Recovery + +- **Difficulty Level:** **Zero Admin Workload (Cryptographic Self-Service)** +- **What you actually have to do:** + - **User Action:** The user visits `https://auth.atyg.org/recover`, types + their 12-word BIP-39 recovery voucher, enters their recovery PIN, and + touches their new replacement YubiKey or phone. + - **Admin Action:** None. +- **Why it's painless:** + - Uses the **2-of-3 Shamir's Secret Sharing (SSS) Matrix**: + - _Share 1 (Device Share):_ Stored in browser IndexedDB, encrypted by + WebAuthn PRF. + - _Share 2 (Hot Share):_ Stored in server PostgreSQL, encrypted with + Argon2id ($t=12, m=64\,\text{MiB}$). + - _Share 3 (Cold Voucher):_ Printed 12-word phrase given to user during + onboarding. + - Combining any 2 shares reconstructs the master secret in client memory to + enroll a new passkey. + - Eliminates insecure SMS/email reset backdoors and relieves admins of manual + account unlock tickets. + +--- + +### Use Case 8: Incident Response & Fleet-Wide Session Revocation + +- **Difficulty Level:** **Low (1-Click / Sub-30µs Mesh Invalidation)** +- **What you actually have to do:** + - Click **"Revoke All Sessions"** for a compromised user or token in the + Auth-Yes management dashboard. +- **Why it's painless:** + - Valkey 8 RESP3 `BCAST` push tracking broadcasts invalidations across all + backend nodes and edge proxies in $<30\mu s$. + - Downstream microservices immediately drop L1 cache entries and sever active + WebSocket feeds without polling loops or database queries. + +--- + +### Use Case 9: Multi-App RBAC & Scope Provisioning + +- **Difficulty Level:** **Low (Web UI Management or Invite Codes)** +- **What you actually have to do:** + - **Option A (Admin Console):** Select User $\rightarrow$ Select Application + $\rightarrow$ Assign Role (`admin`, `operator`, `viewer`). + - **Option B (Automated Onboarding Invite):** Generate a pre-scoped invite + link: + ```bash + curl -X POST https://auth.atyg.org/api/admin/invites/create \ + -H "Cookie: session_id=..." \ + -d '{"appId":"...", "role":"operator", "maxUses":1, "autoActivate":true}' + ``` +- **Why it's painless:** + - New users redeeming the invite link automatically enroll their passkey and + are provisioned with the exact role and scopes for that application. + +--- + +### Use Case 10: Cryptographic Compliance & Tamper-Evident Audit Logging + +- **Difficulty Level:** **Zero Operational Overhead (Append-Only RFC 6962 + Ledgers)** +- **What you actually have to do:** + - Auditors query the cryptographically sealed audit ledger: + ```bash + curl https://auth.atyg.org/api/admin/audit/verify \ + -H "Cookie: session_id=..." + ``` +- **Why it's painless:** + - Every login, invite redemption, scope grant, and session revocation is + hashed into an append-only RFC 6962 Merkle Tree. + - Produces Signed Tree Heads (STHs) and mathematical inclusion proofs. Even an + adversary with direct `root` access to the PostgreSQL database cannot alter + past audit logs without cryptographic detection.
