Node-RED is a programming tool for wiring together hardware devices, APIs and online services in new and interesting ways.
It provides a browser-based editor that makes it easy to wire together flows using the wide range of nodes in the palette that can be deployed to its runtime in a single-click.
This requires modification of the Node-RED settings.js and installing additional Passport-js packages, see [Securing Node-RED](https://nodered.org/docs/user-guide/runtime/securing-node-red#oauthopenid-based-authentication) documentation for further details.

## Preparation
The following placeholders will be used:
-`authentik.company` is the FQDN of authentik.
-`nodred.company` is the FQDN of Node-RED.
### Step 1
In authentik, create an _OAuth2/OpenID Provider_ (under _Resources/Providers_) with these settings:
:::note
Only settings that have been modified from default have been listed.
Take note of the `Client ID` and `Client Secret`, you'll need to give them to Node-RED in _Step 3_.
:::
### Step 2
In authentik, create an application (under _Resources/Applications_) which uses this provider. Optionally apply access restrictions to the application using policy bindings.
:::note
Only settings that have been modified from default have been listed.
:::
- Name: Node-RED
- Slug: nodered-slug
- Provider: Node-RED
Optionally you can link directly to the authentication strategy
Group based permissions are not implemented in the below example
:::
Use npm to install passport-openidconnect
Navigate to the node-red `node_modules` directory, this is dependant on your chosen install method. In the official Node-RED docker container the `node_modules` directory is located in the data volume `data/node_modules/`. Alternatively enter the docker container `docker exec -it nodered bash` and `cd /data/node_modules` to utilise npm within the docker container.
Run the command `npm install passport-openidconnect`
### Step 4
Edit the node-red settings.js file `/data/settings.js` to use the external authentication source via passport-openidconnect.
