Sylvain (ID: 000000b9a8c88831) Voted 4 ★ - Updated 07/01/2020 This seems to work @ 300ms on Keytrack but they were able to get high confidence @ 200ms for me. The Experimental port on Mozilla Addons does not work at all for me however, any chance you can finally port this to Firefox, now that they have a decent WebExtension API?

mytransceiver (ID: 000000b1ad443666) Voted 1 ★ - Updated 11/20/2017 No, as of 2017 Nov, all the "biometric" can over come this tiny trick with over 90% confidence. Even 1000 dwell/delay would not help at all.

Franco GR (ID: 000000ca1c15364c) Voted 4 ★ - Updated 05/25/2017 I've been using this extension for quite a while, both in Firefox and Chrome. It's great.

Puppette Master (ID: 0000000a8266b8dc) Voted 5 ★ - Updated 07/30/2016 With the add-on disabled, converged on a green policy for the id; during testing of the trained id, needed to set add-on to 500 each dwell/delay to confuse the tested id to red reliably. Full training with the add-on enabled at 500 dwell/delay each still converged on a green id policy; also, it still recognized the id during testing with or without the add-on enabled at 500. Full training with add-on at 1000 each converged on a red policy during training, yellow policy during testing, yellow or red identification; during testing, did not matter with or without add-on Unfortunately it seems the only thing that confuses the app is the add-on slowing down my slow connection/processor so much that it cannot get any timing data off the keyboard at all due to the latencies.
