We’ve expanded the functionality of managing Node-RED environment variables by introducing the ability to hide their values in the UI.

#  What’s new?

This feature is supported by both hosted and remote Node-RED instances.

• Users can now designate values as 'hidden' when creating or editing them.
• Hidden values are concealed in the UI for enhanced privacy and security.
• Once marked as hidden and saved:
  • the name cannot be changed.
  • the value can only be updated - its existing value cannot be seen.
• To make a value visible again, users must delete the entry and recreate it as a visible one.

This feature enhances security and allows for more control over sensitive configuration data, ensuring better management in your Node-RED workflows.
