VanGuard: 2FA now offers YubiKey for 2FA

Very neat! The keys are not cheap, but once logged into VG, one can program the Yubikey with your own code.

After that, logging into VG requires:
1- you have the Yubikey in the usb port
2- you click the button on the key
3- VG recognizes the key
4- you have right code.

Foolproof? Probably not but I feel good.
