I'm a noob when it comes to Linux, and I've been using Mint for about a month or so. I've never experienced this issue before, but I typically leave my computer in sleep mode overnight, since I want to be able to quickly continue where I left off the previous day. Today, I woke up my computer, and I did not interact with the computer for around 10 seconds or so, and then suddenly I was logged in without even touching the keyboard. I looked in the settings(login window -> User -> Automatic login), but that field is blank, and I never set it to any value in the past. This is the first time I experience this issue, so I don't know if it was just something temporary or if it might occur again in the future.
Otherwise Mint is great

Thank you.
