On the left navigation menu, click the Administration icon and then on the expanded left menu, select Users. This will display a list of current users under the main organization account (which is the entity that pays for Bocada Cloud).
To remove access for a user, click the trash can icon on the row of that individual which will delete their about to login and use Bocada Cloud.
If you don’t want to remove access/delete the user entirely, you can click the pencil icon to edit their access – you can change or remove a particular role, and/or remove access to one or more organizations. For example, you could change a user’s role from “Editor” to “Viewer.”
