How to add a demo user (Closed)

General

Hi,

I added an admin/password user to the settings file but how do I add a demo/pass user to the ui page?
The demo user can activate the switches but cannot enter into the editing mode.
TIA

UPDATE: Found the solution in the setting.js file.

Actually, I'm new to this as well, I learned it over the past weekend. What helped me is this video at minute 1:20.
These are my changes in the settings.js file. I added a demo user as well who can see and execute the widgets but not modify them.

Have you installed the admin tool and generated the hash password? Also pay special attention to commas and brackets in the settings file.

Also check node-red-log for some hints.

Dear @ebolisa ,

Yes, I had use the node-red-admin to generate hash password, then paste to the settings.js
Totally step by step follow the link you provided.

Best Regards.

7

Can you paste the settings.js file starting from // Securing Node-RED line?

8

Haha, okay. I will re-do it again. :rofl:

9

I ment to copy your file and paste it here starting from the // Securing Node-RED line.
I didn't mean for you to copy and paste my settings.js lines bc will not work.

Sorry, I just re-install the node red. Pasted below.

:thinking: It looks ok. Not sure if I can add much more to this. Try to remove the extra user.

12

Ya, before this I only set to one user. Still same :joy_cat:. Maybe the node-red-admin having generating problem?
I wonder I can use Bcrypt hash generator online or not.
https://bcrypt-generator.com/

13

Not sure, try it! You'll not break it :wink:

14

:sweat_smile: Okay, thanks for your help.

15

Have you noticed the different user name? I'd also use different passwords

16

Also, make sure when you make changes in the settings, to use http://your_up:1880 without any other numbers after restarting the service

17

Okay, my problem solved. Because actually I'm using the Node Red in Siemens Simatic IOT2040. And the node-red-admin version has problem or maybe version too old. I just tried to use the node red on my window install the node-red-admin and generate the hash password and paste it there. Finally, it works! haha :laughing:
Thanks & Regards.

Good!! All problems have solutions except one... death :wink:

Good to know.
I had the same problem as yours yesterday on a new SD card. I didn't waste much time searching for the problem so I removed the node-red app, which came with the OS, and installed a new copy. Modified the settings.js file and the app worked just fine.
