As an administrator, you can customize the Amazon Web Services access portal to meet your organization's needs and ensure users can easily access their authorized resources.

## What you can configure
<a name="what-you-can-configure"></a>

**Amazon Web Services access portal activation**: Set up initial user access to the Amazon Web Services access portal, including user credential activation and first-time sign-in processes.

**Custom Amazon Web Services access portal URL (optional)**: Personalize your organization's Amazon Web Services access portal URL from the default format (`d-xxxxxxxxxx.awsapps.com/start`) to a more recognizable subdomain (`your-company.awsapps.com/start`).

**Before you begin**  
Ensure you have administrative access to IAM Identity Center, verify that IAM Identity Center is set up as either an [organization instance](organization-instances-identity-center.md) or [account instance](account-instances-identity-center.md), and plan your custom subdomain name (this is a one-time configuration that cannot be changed later).

Once configured, users can access the Amazon Web Services access portal using the custom URL and follow the activation process you've established for your organization.
