TypingDNA is obsessed with passive authentication and typing biometrics. Their mission is to improve security without compromising user experience. They started research in 2014 and launched publicly in late 2016. Their technology really shines at being the most available online biometric technology - it works with any keyboard, on any device, works passively behind the scenes, and doesn’t need more than one previous sample to start working. They provide typing biometrics authentication as a service, an API that anyone can use for 2FA and fraud prevention use cases.
