Comment 3 for bug 1451398

My bank uses double identification (website + mobile app). When the mobile app asks for a pin to confirm a payment, it displays the payment information. So I know that the confirmation request comes from the payment I just initiated, and that it's not a random window that pops up from nowhere.

I think the Authentication Dialog should work the same way, displaying information from the originating application, something like:

    The application "foo bar" is requesting authentication for
    "doing this and that".

For example:
==================================
 Authentication request

 The application "Software Update" is requesting authentication for
 "installing gnome-maps, gnome-photos, gnome-foo, gnome-bar"

 Please enter...

 Password: [_____________]
==================================

If the explanation string starts to be long,
there could be a summary string,
and a longuer one in a collapsable container (or alike)

For example:
==================================
 Authentication request

 The application "Software Update" is requesting authentication for
 "installing gnome-maps, gnome-photos, gnome-foo, gnome-bar" and more...
