Static Auth Token Provisioning is used for devices that connect to the Internet over the Ethernet, cellular networks and other connectivity types.
☝️ In this workflow, every product you deliver to the customer will be pre-flashed with Auth Token.
How it works for your customers:
Your happy customers open the box with your product;
Every product comes with the QR code. It can be printed and put into the box, or can be sent over email as a .png image;
After your customers downloaded your app from App Store or Google Play, they create new account and log into your app;
From there they can scan the QR code;
Your app scans the code and saves the Auth Token on the smartphone;
Now smartphone talks to the device with the same Auth Token;
