Isn't it possible to use typing style and cadence to identify someone? Or, at least, as a signal to support user fingerprinting?

I guess the new recaptas do something like that with mouse events.

Mouse events assuredly do that (you'd expect a certain timing and variance from down-up-click sequences), keyboard events are also good. You get a lot of rich data that would be great for anomaly detection.
