I followed

This installation  
[https://nodered.org/docs/getting-started/raspberrypi](https://nodered.org/docs/getting-started/raspberrypi)  
I trying to make it secure following this link:  
[https://nodered.org/docs/user-guide/runtime/securing-node-red#user-permissions](https://nodered.org/docs/user-guide/runtime/securing-node-red#user-permissions)

I Cann't run the following command:'

```auto
node-red-admin hash-pw

```

or

```auto
node -e "console.log(require('bcryptjs').hashSync(process.argv[1], 8));" your-password-here

```

Hopefully some one can help me out?

I installed Node Red on a RPi3 (headless installation).  
Working on a Mac and command line tool installing.

Thank you for your time!  
Robert

Hi @Robert126 - welcome to the forum.

The Pi install script does not install `node-red-admin` (perhaps it should... @dceejay)

So you should first run:

```auto
sudo npm install -g node-red-admin

```

Then you should be able to run the `node-red-admin hash-pw` command.

Hi knolleary,

First of all thank you for your quick response!  
If I do that I get the following:  
**pi@raspberrypi** : **~ $** sudo npm install -g node-red-admin

Despite all those warnings, it has actually installed.

You should now be able to run the `node-red-admin` command.

Rather than add something we had to maintain just for that one command (it really bloated the dpkg install size) - I offered this PR a while back.. [https://github.com/node-red/node-red/pull/1917](https://github.com/node-red/node-red/pull/1917)

Thank you.

But when I they to create a password for an other user  
node-red-john hash-pw  
I get the following  
**pi@raspberrypi** : **/ $** node-red-john hash-pw

-bash: node-red-john: command not found

I created the John user in the settings.js file

Thank you. Sorry for my stupidity.

The usually means you've missed off the comma `,` between `functionGlobalContext` and whatever setting is immediately before it.
