Hello,
I have been using a WPF application connected with SharePoint Online.
The configuration of this Site has been changed. Its configuration now only uses Two factor authentication (Login and SMS).
Also, I have been looking that I should enable with this during the installing process:

Is it possible to call as an iframe with SharePoint Online on WPF?
Thank you!
