# Logging into the web UI

Once you have completed the installation of Sandbox Studio, you can log into the web user interface (UI).

#### Finding the Login URL

The login page is hosted behind an **Amazon CloudFront distribution** that was created during installation. To find the URL:

1. Sign in to the **AWS Management Console** for your **Hub account**.
2. Navigate to **CloudFormation** and open the stack created for Sandbox Studio.
3. Go to the **Outputs** tab.
4. Look for the output parameter named **CloudFrontDistributionUrl**.
5. The value of this parameter is the **login URL** for your Sandbox Studio environment.

**Example:**

<div class="contain-inline-size rounded-2xl relative bg-token-sidebar-surface-primary" id="bkmrk-https%3A%2F%2Fd123example."><div class="overflow-y-auto p-4" dir="ltr">`https:<span class="hljs-comment">//d123example.cloudfront.net</span>`</div></div>Use this URL in your browser to access the Sandbox Studio login page.

#### What Happens Next

- You will be redirected to the **AWS IAM Identity Center (SSO)** sign-in page.
- Log in using your corporate or assigned credentials.
- Once authenticated, you will land on the Sandbox Studio home page (User, Manager, or Administrator view depending on your role).
