How to access iphone app data from a pc if my phone is broken? - 1

Added (1). I have my passwords saved on to an app which I'm pretty sure is backed up on icloud for when I get a new phone -- but I need to access it right now to see what my password is. Is there someway through an emulator or something at all?

I think you can sign in somehow in the Iphone system. Only a guess.

You don't, even if the phone was working app data could only be accessed on the phone itself. On a computer it is stored in a usually hidden encrypted file.
