Home Forums Hardware Mac Desktops & Notebooks New laptop, have give password to restart?

Here new one: I got new Macbook Air, M1 chip.
First first time ever, sometimes, I restart and I get black grey screen asking for computer password. Then goes away new nuisance.

Just double checked and don't have any log in options for that, and have auto log in as I've always had.
Also nothing in security/ privacy I see causing this. Did I miss something, what going on?

Don't have this issue, on my 5 years old imac desktop, only the new laptop: yet both are on on same OS: 11.5.2 Thanks
