Adafruit IO is integrated with your adafruit.com account so you don't need to create yet another online account! You need an Adafruit account to use Adafruit IO because to make sure the data you upload is available to only you (unless you decide to publish your data).

I have an Adafruit.com Account already

If you already have an Adafruit account, then you already have access to Adafruit IO. It doesn't matter how you signed up, your account will make all three available.

To access Adafruit IO, simply visit https://io.adafruit.com to start streaming, logging, and interacting with your data.

Create an Adafruit Account (for Adafruit IO)

An Adafruit account makes Adafruit content and services available to you in one place. Your account provides access to the Adafruit shop, the Adafruit Learning System, and Adafruit IO. This means only one account, one username, and one password are necessary to engage with the content and services that Adafruit offers.

If you do not have an Adafruit account, signing up for a new Adafruit account only takes a couple of steps.

Begin by visiting https://accounts.adafruit.com.

Click the Sign Up button under the "Need An Adafruit Account?" title, below the Sign In section.

This will take you to the Sign Up page.

Fill in the requested information, and click the Create Account button.

For example, to begin working with Adafruit IO, click the IO link between the Forum and LIVE! Links. 

That's all there is to creating a new Adafruit account and navigating to Adafruit IO.
