Is this anything to do with them taking passwords without consent?
I rarely use windows, and when I do one of the first things I do is switch from edge to chrome.
I think I set up edge and used it once to see what it was actually like, but I was pretty careful about the data syncing / sharing settings. I have the Microsoft authenticator app on my phone, I was pretty careful about the privacy settings on that too, but it's been through a couple of phone upgrades.
Somehow all of my passwords were making their way into Microsoft authenticator, so I must have missed something somewhere. I can only imagine how many millions of people must have had their passwords unintentionally slurped by Microsoft if they have been that aggressive with it.
