Hi there,
I'm testing around with NR on docker.
From the docs ([Running under Docker](https://nodered.org/docs/getting-started/docker) and [User Guide: Securing Node Red](https://nodered.org/docs/user-guide/runtime/securing-node-red)) I'm confused about the settings property **credentialSecret**.
What is that? In my understanding it isn't a user password, is a default value used by NR
I come across with the **credentialSecret** property by reading about user credentials and how to set these. and the [docs](https://nodered.org/docs/getting-started/docker#credentials-secrets-and-environment-variables) says:
> Of course you never want to hard-code credentials anywhere, so if you need to use credentials with your Node-RED project, the above Dockerfile will let you have this in your `settings.js` …
>
> `module.exports = { credentialSecret: process.env.NODE_RED_CREDENTIAL_SECRET // add exactly this }`
>
> …and then when you run in Docker, you add an environment variable to your `run` command
> `docker run -e "NODE_RED_CREDENTIAL_SECRET=your_secret_goes_here"`
But it not show an example of a `credentialSecret`. I'm guessing it is a password hash as described by the [docs](https://nodered.org/docs/user-guide/runtime/securing-node-red#generating-the-password-hash). In that case, setting multiples users is impossible.
So my other question is:
Is possible to set multiples user throw environment variables? How so?

Node-RED is not multiuser so this isn’t really a problem :-). @hardillb did post a series recently on how to create a basic multi-user setup using Docker where each user gets their own instance.

`credentialSecret` is nothing to do with user authentication.
It is the key used to encrypt the flow credentials file.

Node-RED uses the `adminAuth` setting to configure user credentials. You would have to set it up in your settings file to get the user/password from environment variables.
[https://nodered.org/docs/user-guide/runtime/securing-node-red](https://nodered.org/docs/user-guide/runtime/securing-node-red)
But as Dave says, Node-RED is not multi tenent - the runtime runs one set of flows. If you have multiple users configured, they all see the same flows.
