I use the Onedrive app to share files secure to my customers. In the webversion it's possible to send with password an expiration link.
it would be perfect if this is also possible in de desktop app.

also if this option is available for all the options, so not only when you share a link for everyone. also specific adresses.

in this way it is even more secure. now you can still send to the wrong email, so I see no difference with just sending as an attachement.
