Weird Password/iCloud stuff going on - baffled. "This is impossible."
This might just be a simple service outage or a migration to move iCloud data to a new container or migrate it to make it ready for the fall iOS and macOS releases and new features that ran into a glitch.

The same way thing has happened to me recently. Yesterday I had stuff in my iPhone analytics dating back to July,8th. I went to show them to a coworker today and 80% of them were gone. I don’t have any idea how, that coupled with some other stuff has me worried that’s it’s nefarious.  

I also feel as though somebody has reported me to the police and that I am now listed as an aggressive or dangerous person. So it's not at all odd to feel what you're feeling so I wanted to post that you're not alone in this take.
