Simply put, I want to stay signed in to Apple ID on my iPhone 8, but I don't want the contents of my iCloud Drive to be accessible on the phone. At the very least, I would like there to be an additional security barrier to access the iCloud Drive, something more than just having to enter my passcode to get past the lock screen.
At present, it seems like anyone who knows my phone's passcode can open the phone and go directly to Files, then tap "iCloud Drive," and then have direct access to my entire iCloud Drive contents.
The issue is that one other person does have access to my phone's passcode, and I want to keep it that way, but I don't want that person to have access to my iCloud Drive. Touch ID doesn't seem to be available for blocking access.
Have I missed something? Is there nothing I can do to keep my Drive more private? I don't want to stay signed out of Apple ID, that would be inconvenient and disadvantageous for multiple reasons.
Thanks to anyone who knows.
