But how do you know that it is your session? That's the whole point of a secure access key. Somebody could have killed your session, logged in and started an imitation of the display manager login window.

If somebody logged in, disabled terminate sequence and started login screen emulation, you'll notice, that nothing happens when you press Ctrl-Alt-BS. :) But I agree that "Secure Access Key" (Alt+SysRq+K on Linux) is better for that, and it works both for text and X terminals. It's just some distributions disable Magic SysRq keys, while C-A-BS usually works everywhere during login screen.

Well, the fake login prompt can of course be programmed to react to ctrl-alt-backspace.
