# Add or remove portal users in AWS IoT SiteWise
<a name="portal-change-users"></a>

**Note**  
The SiteWise Monitor feature is no longer available to new customers. Existing customers can continue to use the service as normal. For more information, see [SiteWise Monitor availability change](https://docs.aws.amazon.com/iot-sitewise/latest/appguide/iotsitewise-monitor-availability-change.html).

You choose which users have access to your portals. Portal users appear in the list of users within a SiteWise Monitor portal. From this list, portal administrators can add project owners, and project owners can add project viewers.

**Note**  
Your portal administrators and portal users might contact you through a portal's support email if they need you to add or remove a user.

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

#### [ IAM Identity Center ]

If you use IAM Identity Center as your identity store, and you're signed in to your AWS 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 a user.
