  • Hi,

    By default for SharePoint Online, the Modern Authentication is tuned on.

    When Office 2013 client apps without modern authentication enabled connect to SharePoint Online, it uses Basic Authentication as authentication behavior. It does not understand modern authentication when connect to the SharePoint Online with modern autnentication and you will get the authentication error.

    To resolve it, you need to enable modern authentication for Office 2013 client apps including SharePoint Designer 2013.

    To enable modern authentication, you need to set the following registry keys. The keys have to be set on each device that you want to enable for modern authentication:
