It's a key or keycombination that is guaranteed to take you to
a login prompt regardless of what other programs are currently
running. This is useful for example if someone writes a password
sniffer that looks exactly like the login-screen. Such a program
could be made to ignore CTRL-C as well as other signals, so you
can't tell if it's a real login-screen or not.

SAK gives you an easy way to know that you really are looking
at a real login-screen.
