Yes. This is from that page:
>>While you type, the keyboard quietly records how you type — the rhythm, the pauses between keys, where your finger lands, how hard you press.
>>Nobody types the same way. Your pattern is as unique as your handwriting. That's the signal.
This very precisely makes my point:
Yes, the typing pattern of any human is highly and possibly even completely unique to that human — UNTIL any of a myriad of everyday issues makes it falsely deny access because the human's typing pattern has changed in a way the human can't do anything to fix at the moment.
If you are only attempting to distinguish a human from an automated system, it'll be better, until someone just starts recording the same patterns and re-playing them to this upstream process; then its a mere race to who can get their hooks in at a lower level. And someone is always going to say: "Oh, this system can identify the specific human", and we're off to the races again.
So, no. Unless you can account for ALL of the reasonable everyday failure modes, typing with either hand, any finger or combination of fingers out of commission for a minute or a lifetime, this idea will fail.
Then why does your link claim the following?
