# AltTextLab - How do I link my account?

## Overview

To authenticate with AltTextLab, you need:

1. **API Key** — an AltTextLab API key.

This guide will show you how to create one.

### Prerequisites

* An AltTextLab account. You can start free with 25 credits. If you don't have an account, [sign up](https://app.alttextlab.com/sign-up).

### Step 1: Create an API key

1. Sign in to the [AltTextLab dashboard](https://app.alttextlab.com/sign-in).
2. In the left sidebar, under **Connect**, click **API keys** ([direct link](https://app.alttextlab.com/settings/api-keys)).

3. Click **Create API key**.

4. Enter a name for the key. You can also set a monthly usage limit, or leave it at **No limit**. Then click **Create key**.

5. Click **Copy** to copy the key and save it right away. It is shown only once.

### Step 2: Enter your API key in the Connect UI

1. Open the form where you need to authenticate with AltTextLab.
2. Enter your key in the **API Key** field.
3. Submit the form. The connection is saved without checking the key: if the key is wrong, the first API request returns an authentication error.

You are now connected to AltTextLab.
