+## Authentication
+
+Zerobyte uses [better-auth](https://github.com/better-auth/better-auth) for authentication and session management. The authentication system automatically adapts to your deployment scenario:
+
+### Cookie Security
+
+- **IP Address / HTTP access**: Set `BASE_URL=http://192.168.1.50:4096` (or your IP). Cookies will use `Secure: false`, allowing immediate login without SSL.
+- **Domain / HTTPS access**: Set `BASE_URL=https://zerobyte.example.com`. Cookies will automatically use `Secure: true` for protected sessions.
+
+### Reverse Proxy Setup
+
+If you're running Zerobyte behind a reverse proxy (Nginx, Traefik, Caddy, etc.):
+
+1. **Set `BASE_URL`** to your HTTPS domain (e.g., `https://zerobyte.example.com`)
+2. The app will automatically enable secure cookies based on the `https://` prefix
+3. Ensure your proxy passes the `X-Forwarded-Proto` header
+
+### Important Notes
+
+- The `BASE_URL` must start with `https://` for secure cookies to be enabled
+- Local IP addresses (e.g., `http://192.168.x.x`) are **not** treated as secure contexts by browsers, so secure cookies are disabled automatically
+- `localhost` is treated as a secure context by browsers even over HTTP, but we still recommend using `BASE_URL` for consistency
+- If you don't set `BASE_URL`, the app will work but may have issues with callback URLs in certain authentication flows. All cookies will be set with `Secure: false`.
