Quick Reference Guide

Password potect your Node-RED App (any version)


By default, your Node-RED App from the PLCnext Store is not secured - anyone who can access its IP address and port can access the editor and deploy changes.

This is only suitable if you are running on a trusted network.

To password protect the App follow the below steps:

  1. Connect your EPC to the internet. To do so, please follow this chapter: Connect EPC to internet.
  2. Install the "node-red-contrib-bcrypt" node using the palette manager.
  3. Import the Password_hash.json flow.
  4. Update the payload "Password Node" with the password.
  5. Deploy and start the flow. Inject the payload. The hashed value will be in the debug window.
    Password_Node_Hash
  6. Update "/opt/plcnext/appshome/data/60002172000678/volumes/node-red/settings.js" with the hashed password above. Make sure to uncomment the setting:
    Password_Node_Hash2
  7. Reboot your device.
  8. Open up your Node-RED editor on your EPC again. You should now see a login required.
    Password_Node_Hash3
  9. You can logout by selecting the "preson" icon in the upper right window.
