Our clients are confused by the Box SSO that says, "If you are not part of [Our Company], continue to log in with your Box.com account." They believe they ARE part of our company, so they often select the other option meant for our employees.

Can you either change your SSO language so the left says Employees of [*** Company] and the right says [Clients of or 3rd Parties to *** Company]?

The other option would be to make this language editable in the Admin Console.
