Yup. It's the little keychain frob that gives you a string of numbers,
updated every 30 seconds or so, which stays roughly in sync with a server,
so you can use them as one-time passwords
instead of storing a password that's good for a long term.
So if the phisher cons you into handing over your information,
they've got to rip you off in nearly-real-time with a MITM game
instead of getting a password they can reuse, sell, etc.
That's still a serious risk for a bank,
since the scammer can use it to log in to the web site
and then do a bunch of transactions quickly;
it's less vulnerable if the bank insists on a new SecurID hit for
every dangerous transaction, but that's too annoying for most customers.
