# Authentication

In order to use the [Workers API](/toolhouse/developers/workers-api.md) you'll need to authenticate using a Toolhouse API key.

You can see the API key in the [API Keys section](https://toolhouse.app/settings/api-keys) or by navigating to your user menu and selecting **API Keys.**

The first API key is generated for you when you sign up for Toolhouse.

### Adding a new API key

1. Go to the [API Keys section](https://toolhouse.app/settings/api-keys) or by navigate to your user menu, then select **API Keys.**
2. In the **Generate new API key** section, type a name for your API Key. Give the key a recognizable name so you can reference it later
3. Click **Generate.**

### API key security

API Keys are encrypted both in transit and at rest in the Toolhouse platform.

{% hint style="info" %}
Toolhouse will never ask you to share API keys or other sensitive details.
{% endhint %}

### More ways to authenticate

By default, Toolhouse manages authentication for you. Customers on the Enterprise plan can implement custom authentication models based on their approved security policies. Talk to the Toolhouse team for more information.
