What is Keystroke Dynamics?

Keystroke dynamics tracks the timing of a user’s typing patterns—the latency of presses and releases, flight times between keys, error rates, and so on, including features of copy/paste events. It’s a form of behavioral biometrics that requires no specialized hardware. A model establishes a behavioral profile over many sessions, against which new logins or high-risk behaviors are scored. Reusing the same credentials across different individuals results in a drift from the baseline behavior.

Program best practices: enroll passively over time; use segmented profiles for different devices; cap the sensitivity to support accessibility needs. Store derived features, not raw input text, and keep retention periods short. When behavior really does look like the “wrong person” try a different channel – adding a selfie with liveness or routing to full identity verification before allowing payouts or account recovery. You’re building quiet confidence, not suspicion.
