+
+### Authentication
+- Default behavior: CodeNomad requires a login (username/password) and stores a session cookie in the browser.
+- `--dangerously-skip-auth` / `CODENOMAD_SKIP_AUTH=true` disables the login prompt and treats all requests as authenticated.
+  Use this only when access is already protected by another layer (SSO proxy, VPN, Coder workspace auth, etc.).
+  If you bind to `0.0.0.0` while skipping auth, anyone who can reach the port can access the API.
 
 ### Data Storage
 - **Config**: `~/.config/codenomad/config.json`
 - **Instance Data**: `~/.config/codenomad/instances` (chat history, etc.)
