Hi, I've created the user pi and added it to sudoers (but not on root group), I've installed NR under this user, recently it started asking me password during boot, why? Maybe a module needs that?  
After putting passowrd I have a "Starting as a systemd service"

In order to start Node-red as a systemd service, the node-red-start script calls **sudo systemctl start nodered**. This is the step that is asking for your sudo password.

If you want to avoid this prompt, either setup passwordless sudo for the pi user or else use **sudo systemctl enable nodered** (once) which will start Node-red automatically when the device boots.

ps I have been using Node-red for several years and this is the first time I have ever used **node-red-start** and **node-red-stop**.  
Instead I use **sudo systemctl enable node-red** , **sudo systemctl stop nodered** , etc

thank you for your kind reply 🙂 for now I don't need to start it automatically, as I'm testing other things and sometimes I reboot. The solution is to call NR with node-red instead of node-red-start, in this case it doesn't ask for pasword 🙂

The advantage of using node-red-start is that you don't have to keep the terminal window with node-red running in it open. You can break out of the log that is shown when you run node-red-start and node-red will keep running in the background.  
Also, as suggested, if you run `sudo systemctl enable nodered` then it will start for you automatically on boot so you don't have to do anything at all. Then you can restart node-red if you need to using  
`node-red-stop`  
`node-red-start`  
or just  
`node-red-reload`

Thank you my dear friends, the question was silly, the problem comes because distractly I used once node-red and later node-red-start, I've made confusion with Windows, I haven't known there is node-red also for linux and could start it without the service, so I guessed it was a module asking for a permission.  
All ok 🙂
