Futuristic Security schemes could kill passwords

The idea is coming and looks more possible to be realized today. Pentagon’s DARPA is stepping to get rid of countless passwords and replace it by human factors, not fingerprints or iris scan, but individual’s language patterns, typing speed, or computer keystrokes. That’s being said, a computer user can come back from coffee break and start typing again with no password and the software developed by Pentagon’s DARPA can recognize the person based on factors such as his typing speed or Google search patterns or lock him out of the system that reflect an unauthorized user. But the system will be designed to the department of defense first before reaching the commercial interest. Nice idea I believe because we don’t need to remember bunch of passwords anymore
