# Avalara - How do I link my account?

# Overview

To authenticate with Avalara, you will need:

1. **User Name** - The User Name associated with your Avalara AvaTax account, used to authenticate API requests. Alternatively, you can use your **AccountID** instead of a **User Name**.
2. **Password** - The password linked to your Avalara AvaTax account, required for secure authentication. Alternatively, you can use your **License Key** instead of a **Password**.
3. **AvalaraClient** - A key that can help you diagnose and resolve issues with your software.

This guide will walk you through finding or generating the **Account ID/License Key** pair within Avalara.

### Prerequisites:

* You must have a registered account with Avalara.
* Only account administrators can generate the **Account ID/License Key** pair.

### Instructions:

#### Step 1: Finding Your Pair Keys

1. You can use your **username/password** pair for authentication, or alternatively, opt for the **Account ID/License Key** pair. To obtain the later credentials, **log in** to your Avalara dashboard.
2. Navigate to **Settings** and select **License and API Keys** to obtain both the **Account ID** and the **License Key**. Under the License Keys tab, click on **Generate New Keys** to create new credentials.
