<a name="edit-environment-profile"></a>

In Amazon DataZone, an environment profile is a template that you can use to create environments. For more information, see [Amazon DataZone terminology and concepts](datazone-concepts.md). To edit an existing environment profiles in an Amazon DataZone domain, you must belong to an Amazon DataZone project. 

**To edit an environment profile**

1. Navigate to the Amazon DataZone data portal URL and sign in using single sign-on (SSO) or your AWS credentials. If you’re an Amazon DataZone administrator, you can navigate to the Amazon DataZone console at [https://console.aws.amazon.com/datazone](https://console.aws.amazon.com/datazone) and sign in with the AWS account where the domain was created, then choose **Open data portal**.

1. Within the data portal, choose **Browse projects** and select the project in which you want to edit the environment profile.

1. Navigate to the **Environments** tab within the project, then choose **Environment profiles**, and then choose the environment profile that you want to edit.

   If you are editing a Data Warehouse environment profile, you can only edit the name and the description of an existing environment profile.

   If you are editing a Data Lake environment profile, you can edit the name and the description of the profile and you can also edit the projects that are authorized to use this profile to create environments and you can edit databases. To edit these settings, do the following:
   + In the **Authorized projects** section, specify the projects that can use the environment profile with the built-in Data Lake environment profile for creating environments. By default, all projects within the domain can use the data lake blueprint in the account to create environment profiles. To keep this default setting, choose **All projects**. However, you can restrict this by assigning projects to the blueprint. To do so, choose **Authorized projects** only and then specify projects that can use this project profile to create environments.
   + In the **Databases** section, either choose **Any database** to enable publishing from any database within the AWS account and region where the environment is created or choose Only default database to enable publishing from only the default publishing database that is created with the environment.

   When you complete your edits, choose **Edit environment profile**.
