# Addressfinder - How do I link my account?

## Overview

To authenticate with Addressfinder, you need:

1. **API Key** — the public key of your Addressfinder project.
2. **API Secret** — the secret paired with that key.

This guide will show you how to find them.

### Prerequisites

* An Addressfinder account. If you don't have one, [sign up for the 30-day trial](https://portal.addressfinder.net/signup/au/au_business_trial). No credit card is required.

### Step 1: Open the Keys page

Log in to the [Addressfinder Portal](https://portal.addressfinder.net) and click **Keys** in the left sidebar, under your project.

### Step 2: Copy your key and secret

On the **Credentials** page, open the **API keys** tab. Your project already has a key and secret pair.

1. Copy the value in the **Key** column. This is your API key.
2. Click **Show secret**, then copy the value in the **Secret** column. This is your API secret.

### Step 3: Enter your key and secret in the Connect UI

1. Open the form where you need to authenticate with Addressfinder.
2. Enter your key in the **API Key** field and your secret in the **API Secret** field.
3. Submit the form, and you should be successfully authenticated.
