# Doppler - How do I link my account?

## Overview

To authenticate with Doppler, you need:

1. **API Token** — a Doppler Personal, Service or Service Account token.

This guide will show you how to get it.

### Prerequisites

* A Doppler account. API access is included on the free Developer plan. You can [sign up here](https://dashboard.doppler.com/register?plan=developer).

### Step 1: Generate a Doppler token

Use a **Personal Token** to give the connection your own access to every project, or a **Service Token** to limit it to one config.

**Personal Token** (starts with `dp.pt.`):

1. Sign in to the [Doppler dashboard](https://dashboard.doppler.com).
2. Click **Tokens** in the left sidebar, open the **Personal** tab, and click **Create a personal token**. Then click **Create** in the dialog.

3. Copy the new token with the copy button. It is only shown once.

A Personal Token has the same read and write access as your Doppler account.

**Service Token** (starts with `dp.st.`):

1. Open the project and select the config you want to connect.
2. Go to the **Access** tab and generate a service token. Name it, and enable write access only if your integration needs it.
3. Copy the token. It is only shown once.

A Service Token gives read-only access to that one config, unless you enabled write access. See [Service tokens](https://docs.doppler.com/docs/service-tokens).

**Service Account token** (starts with `dp.sa.`, Team and Enterprise plans): go to **Team** -> **Service Accounts**, open the service account and click **+** next to **Service Account API Tokens**. See [Service accounts](https://docs.doppler.com/docs/service-accounts).

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

1. Open the form where you need to authenticate with Doppler.
2. Enter your **API Token** in the designated field.
3. Submit the form, and you should be successfully authenticated.

You are now connected to Doppler.
