LaunchUriAsync with authentication

Question

I have the following line of code opening a document from a Sharepoint document library

 await Windows.System.Launcher.LaunchUriAsync(uri, options);

Everthings works fine, but when I open a document (let it just say a document with text), the user must put his username / password before any interaction with the document.

Can I add authentication information in LaunchUriAsyncMethod?

thanks for the help
