For the past few days I have been getting a
"Session locked by user"
message with only user can unlock this session.
That could be the screensaver (TCC > appearance > screen saver).
"Below that is a check box labeled Require password to stop screen
saver. If it is checked, when you click a key or click a mouse button
to end the screen saver and return to your work, you must enter a
password."
