I have had this experience - I think! Years ago (like mid 1990's) I set up what was then a primary workstation in a shared office facility not controlled by myself for a few weeks while working on a project.
After returning the machine to my own office, I was blocked by a password request!
I removed the CMOS battery and jumpered the line to ground, reset to defaults and started life over. I never knew for sure who or how, but for a while afterward I always set my own BIOS password for that reason... but I have dropped the habit, not much of an issue for me these days.
