After installing a number of apps onto my new NVMe SSD, I rebooted and, surprisingly, I looked into my user account without entering my passcode. Not sure how or why that happened but it is a bit disconcerting were someone else able to do that.
I’ll have to test that when I get home tonight. What I found really strange is, when disconnecting the battery and after installing my NVMe SSD, I buttoned up the bottom and then opened up the display. It was already booted up! Now that was strange.
