# Adafruit IO - How do I link my account?

## Overview

To authenticate with Adafruit IO, you need:

1. **Username** — your Adafruit IO username.
2. **Adafruit IO Key** — the key of your Adafruit IO account.

This guide will show you how to get them.

### Prerequisites

* An Adafruit account. [Sign up](https://accounts.adafruit.com/users/sign_up) for free if you don't have one.

### Step 1: Copy your username and Adafruit IO Key

1. Sign in to [Adafruit IO](https://io.adafruit.com/).
2. Click the golden key icon in the top navigation bar, next to **New Device**.

3. In the **Your Adafruit IO Key** pop-up, copy your **Username** and your **Active Key**.

> [!WARNING]
>
> Clicking **Regenerate Key** immediately invalidates your old key, so connections that use it stop working.

### Step 2: Enter your credentials in the Connect UI

1. Open the form where you need to authenticate with Adafruit IO.
2. Enter your username in the **Username** field and your key in the **Adafruit IO Key** field.
3. Submit the form, and you should be successfully authenticated.
