#6 Chris quote:
4. Go to "System" -> "Administration" -> "Users and Groups".
5. Change password from "Asked on logon" to "Not asked on logon".
6. Lock your machine.
7. Press "Switch User".
8. Observe no password is required to unlock as the current user.

I confirm this issue on Ubuntu Mate 20.04.0 in a virtual machine. I can reproduce it each times.
