# Invite administrators in SiteWise Monitor
<a name="monitor-invite-administrators"></a>

To get started in your new portal, you must assign a portal administrator. The portal administrator creates projects, chooses project owners, and assigns assets to projects. Portal administrators can see all of your Amazon IoT SiteWise assets.

Based on the user authentication service, choose one of the following options:

------
#### [ IAM ]

You can choose a user or role to be the portal administrator. If you want to add another user or role as a portal administrator, you can create a user or role in the IAM console. For more information, see [Creating an IAM user in your Amazon account](https://docs.amazonaws.cn/IAM/latest/UserGuide/id_users_create.html) and [Creating IAM roles](https://docs.amazonaws.cn/IAM/latest/UserGuide/id_roles_create.html) in the *IAM User Guide*.

**To invite administrators**

1. Do the following:
   + Choose **IAM users** to add an IAM user as your portal administrator.
   + Choose **IAM roles** to add an IAM role as your portal administrator.

1. Select the check boxes for the users or roles that you want as your portal administrators. This adds the users or roles to the **Portal administrators** list.

1. If you add a user or role that you don't want as an administrator, clear the check box for that user or role.

1. When you're finished inviting portal administrators, choose **Next**.

**Important**  <a name="iam-portal-user-permissions"></a>
Users or roles must have the `iotsitewise:DescribePortal` permission to sign in to the portal.

**Note**  
If you use IAM Identity Center as your identity store, and you're signed in to your Amazon Organizations management account, you can choose **Create user** to create an IAM Identity Center user. IAM Identity Center sends the new user an email for them to set their password. You can then assign the user to the portal as an administrator. For more information, see [Manage identities in IAM Identity Center](https://docs.amazonaws.cn/singlesignon/latest/userguide/manage-your-identity-source-sso.html).

------

You can change the list of portal administrators later. For more information, see [Add or remove portal administrators in Amazon IoT SiteWise](portal-change-admins.md).

**Note**  
Because only a portal administrator can create projects and assign assets to them, you should specify at least one portal administrator.

As the last step, you add users who can access your new portal.
