My (European) bank uses "memorable information", an alphanumeric string
provided by me, and they ask for three randomly chosen characters when
authenticating online. There is also a fixed password.
Not terribly secure, or terribly one-time, but it would defeat a simple
keylogger or shoulder surfing attack, for instance. It doesn't give me the
warm fuzzies, but it does mean I would use a dodgy terminal at least once if
I was stuck in the badlands (and then change passwords etc.).
