i‘m glad you learned about how to switch tty!
now this is a very rare situation, but if you log into your computer, then switch to some tty, log in there too, do things, lock it, and leave the computer, the other tty is still unlocked because you need to lock both the tty you logged into.
i know this is a super rare/ hypothetical situation, but i think you should know.
god at first i saw only the first line cuz the second was cut off. the relief i felt upon scrolling XD
