+Note (required): To establish a bridge connection the plugin now requires three credentials to be provided and saved in the WordPress settings: **Email**, **Password**, and **API Key**. All three are stored as options (`igny8_email`, `igny8_access_token`/`igny8_refresh_token`, `igny8_api_key`) — the API key is stored using secure storage helpers when available. The bridge will refuse connection if any of these are missing.
