Production Authorization

This topic describes how to get the license and write it to the device.

License

The license is an encryption certificate issued by Tuya to allow a device to connect to the Tuya IoT operating system. Each device must be assigned a unique license for authentication. A license grants permission for a single device to connect to and access the cloud.

Get license

You can request a free license or purchase one.

• Request free license
• Purchase license

Write license

The license is delivered in a spreadsheet, including UUID and authkey. The license is in plain text and generated when you pick up the order. You are responsible for managing the key pair. During production, you write the license to each device using your tool.

How to use

You need to write a script program for writing the license to the device. After a product is tested, you write a pair of keys into each device through your own server.
