# Sauce Labs

> Run Testsigma tests on Sauce Labs cloud devices by connecting your existing Sauce Labs account.

Sauce Labs integration runs Testsigma tests on Sauce Labs cloud devices. Author web, mobile web, and mobile tests as usual, then pick it as the test lab for a run.

## Prerequisites

- Your Sauce Labs **username** and **API key**, from the account dashboard.

## Connect your account

1. **Open the integration**: under **Settings > Integrations**, on the **Test Lab** tab, enable **Sauce Labs**.

2. **Enter your credentials**: in the **Sauce Labs details** dialog, enter the username and API key from Sauce Labs, then confirm the key.

3. **Save**: click **Save & Enable**.

To update credentials or remove the lab, click **Manage** on the widget.

## Select Sauce Labs in a run

When you create an ad-hoc run or a test plan machine profile, select **Sauce Labs** as the **Test Lab** type instead of Testsigma Lab. The run then executes on Sauce Labs cloud devices.
