+## What is Node-RED
+
+From https://nodered.org/
+
+:::note
+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.
+:::
+
+:::warning
+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.
+:::
+
+-   Name: Node-RED
+
+**Protocol Settings**
+
+-   Redirect URIs/Origins (RegEx): https://nodred.company/auth/strategy/callback/
+-   Signing Key: Select any available key
+
+:::note
+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
+
+-   Launch URL: https://nodred.company/auth/strategy/
+
+### Step 3
+
+:::note
+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.
+
+```js
+adminAuth: {
+type:"strategy",
+strategy: {
+        name: "openidconnect",
+        label: 'Sign in with authentik',
+        icon:"fa-cloud",
+        strategy: require("passport-openidconnect").Strategy,
+        options: {
+                issuer: 'https://authentik.company/application/o/<application-slug>/',
+                authorizationURL: 'https://authentik.company/application/o/authorize/',
+                tokenURL: 'https://authentik.company/application/o/token/',
+                userInfoURL: 'https://authentik.company/application/o/userinfo/',
+                clientID: '<Client ID (Key): Step 2>',
+                clientSecret: '<Client Secret: Step 2>',
+                callbackURL: 'https://nodered.company/auth/strategy/callback/',
+                scope: ['email', 'profile', 'openid'],
+                proxy: true,
+        verify: function(issuer, profile, done) {
+                done(null, profile)
+        }
+      }
+    },
+    users: function(user) {
+        return Promise.resolve({ username: user, permissions: "*" });
+    }
+},
+```
