I've found yubikey fairly interesting re: another factor for authenticaton
for quite a while now. You can do otps or static keys on the same usb device
that reads as a keyboard for inputting the desired key.
iirc redhat and debian have support for yubikeys baked in...

Subject: [dm-crypt] question on available userspace authentication methods
This is mostly question on cryptsetup, if this is a wrong list, i'd be
thankful for information where is the proper mailing list for it.
Hi list, i've been using dm-crypt through cryptsetup for quite a while
now. So far my impression is that your authentication is limited to
either providing a keyfile, or typing in a password to unlock
encrypted volumes. Maybe there are more ways to authenticate, and i am
just not aware of it.
Are there any other authenticaton methods one could use?
I'm mostly interested in whether somebody is planning to adapt
cryptsetup to authenticate using an USB microcontroller device
(teensy, arduino, atmel) ? Having a physical key device that's not
just a flashdrive with a plain key on it (either as a file or data
hidden in a few sectors (archilinux has such option)) would sound a
bit more reasonable..
