# Associate Users with Business Units

In Enterprise 2.0 accounts, an admin can add users to Marketing Cloud Engagement business units. Users who have access to multiple business units can switch between business units manually after they log in.

1. From Setup, in the Quick Find box, enter users, and then select **Users**.
2. Select a user, and click **Manage Business Units**.
3. Under Default Business Unit, select a default business unit for the user. For standard users, the business unit that you select is the one that the user sees when they log in. For API users, the business unit that you select is the one that their API requests operate in. If the user has access to other business units, they can interact with the business units by specifying the `Options.Client.Id` property in SOAP API requests.

    Note
    
    If you select the enterprise business unit for an API user, they can use SOAP API to access all of the child business units in the enterprise. To limit business unit access for SOAP API users, select a child business unit as the default.
4. To give the user access to additional business units, select them under Associated Business Units.

    Note
    
    If you select additional business units, the user’s default business unit is selected and can’t be removed from the Associated Business Units section.
5. Save your changes.
