An indication on existing links to know if Recipients need to sign in option was used
I have been unable to find any way to determine if the option "Recipients need to sign in with a Microsoft account" was used when sharing some items. I see the items listed when navigating to the OneDrive "Shared > Shared by me" screen. I can check the box in the upper right corner of an item and in the properties pane at the right under Sharing, I can see a persons name listed. I can click on that name and a modal Share dialog appears over the screen. Under the person's name there is a drop down box that has "Change to view only" and "Stop sharing" listed. I do not see anywhere on the screen any indication that lets me know if I had selected the "Recipients need to sign in with a Microsoft account" when I originally invited the person to share.
So as it is now I am unable to determine which type of link that person has. I realize that I can ask the recipient to test the link, or stop sharing and then send a new link to the recipient, making a note of which option that I select. That is not the point of this suggestion.

There is no more "need to sign in" option. https://onedrive.uservoice.com/forums/262982-onedrive/suggestions/13455546-onedrive-just-got-less-secure-really-sad-to-see-t
