Hello Aaron

You can disable the user account in the directory of your cloud provider. For example, if you are using Azure Databricks, then you will manage the users via Azure Entra. Then you can simply deactivate the user account in Entra, for example, by unchecking the “Account enabled” button.

If you want the user to remain active in the cloud after all and just not be allowed to access Databricks Workspace, you can remove them from the workspace.

The user is not deleted in Entra, but merely removed from the workspace. It can still be found in the account.
