OpenSign is an authentication app designed to integrate with NH농협 Banking Service when using it on a mobile web. The app is developed by 농협BANK and is available for free on the Android platform.

To use the app, two necessary access permissions need to be granted. First, the app requires access to storage to issue certification and login. Second, the app needs access to the device's information to prevent electronic financial fraud.

The app's access permissions can be managed by going to Settings > Application Manager > NH OpenSign > Permission Menu.

For any further questions or assistance while using the NH Smart Authentication app, users can contact the NH농협 Customer Happiness Center atorconnect toThank you.
