ESP8266 NodeMCU and Arduino IoT Cloud

Hi!
Can I connect my ESP8266 NodeMCU boards in the Arduino IoT Cloud?

Hello,

if I recall correctly, the NodeMCU is missing a critical component required for authenticating devices to the IoT Cloud: the crypto chip required for the secure authentication standard we are using.
This means that technically you can connect your boards to the IoT Cloud, but they would not be able to authenticate properly.

At a later stage we plan to open up to less secure devices implementing a less strict encryption and less secure authentication.
