Researchers at Iowa State University are exploring the concept of keystroke authentication as a way to replace passwords, reports CNET.

Associate professor of engineering Morris Chang is working with a team to identify people by their typing methods and keystroke speed. The goal is not just to authenticate someone logging into a website or system, but also to continuously monitor their activity while at that site to ensure an account hasn’t been hijacked.

Currently, this type of keystroke authentication has a high false positive rate because different activities may throw off a person’s typing rate; however, the researchers will continue to explore this method to discover its viability as a way to authenticate that can’t be stolen.
