Remove WIA from ADFS login

Hello all,

I currently have ADFS 3.0 running (2012 R2 of course) with Office 365. When an internal user opens Outlook.office365.com he is redirected to ADFS which then uses WIA to login. This is fine in most circumstances, but we have many shared computers. How do I change the ADFS login page to not use WIA?

Thanks,

Paul
