So I like the new iCloud Drive app, as it's much easier and quicker to update docs than when having to pull them from iCloud in individual apps (think about how slow it is for Numbers to grab an Excel spreadsheet from iCloud). So I like the app, much cleaner and simpler and easier to use. However, is there any way to require touch ID/passcode to launch the app? My concern here is that I only really use iCloud Drive to access a spreadsheet on the go with all of my various account information/passwords for bills, banking, etc. If I had my phone out and I was using it, and someone came by and ripped it out of my hand while unlocked, they could theoretically go into iCloud Drive and get my account spreadsheet and have a free for all. As such, I think that even if the phone is unlocked, to actually access the iCloud Drive app (or anything in iCloud via the individual apps) there should be an additional authentication required. Is there a way to do this? I don't see anything in settings, and right now it looks like anyone could get my spreadsheet through the iCloud Drive app, or directly via the Numbers app if they stole my phone while it was unlocked.
