What's something we often use for security in the real world but not online? PIN codes. We use them at stores, banks, and ATMs, so why not use them online?

But PINs are still a password and can be just as good with the right precautions.
Some companies are using PIN codes to add an extra layer of security on top of what sites already offers. Here are four companies at the FinovateStartup conference doing just that.
