-## 🔐 Admin Mode (Single-User)
-
-For self-hosted or single-tenant setups, NOFX supports a strict admin-only mode that disables public features and requires an admin password for all access.
-
-### How it works
-- All API endpoints require a valid JWT when `admin_mode=true`, except:
-  - `GET /api/health`
-  - `GET /api/config`
-  - `POST /api/admin-login`
-- Logout invalidates the current token via an in-memory blacklist (sufficient for single instance; use Redis for multi-instance – see Notes).
-
-### Quick setup
-1) Set flags in `config.json`:
-```jsonc
-{
-  // ... other config
-  "admin_mode": true,
-  "jwt_secret": "YOUR_JWT_SCR" 
-}
-```
-
-2) Provide required environment variables:
-- `NOFX_ADMIN_PASSWORD` — plaintext admin password (only used at startup to derive a bcrypt hash)
-
-Docker Compose example (already wired):
-```yaml
-services:
-  nofx:
-    environment:
-      - NOFX_ADMIN_PASSWORD=${NOFX_ADMIN_PASSWORD}
-```
-
-1) Login flow (admin mode):
-- Open the web UI → you’ll be redirected to the login page
-- Enter admin password → the server returns a JWT
-- The UI stores the token and authenticates subsequent API calls
-
-### Notes
-- Token lifetime: 24h. On logout, tokens are blacklisted in-memory until expiry. For multi-instance deployments, use a shared store (e.g., Redis) to sync the blacklist.
