Replacing passwords - easier tech than done

Replacing passwords has become a bit of a holy grail for cyber security startups. About 5 years ago I first came across a company proposing typing characteristics as a biometric login, and there seem to be a number of companies attempting something like that still. At VentureFest Bristol I came across PixelPIN who use images to replace passwords, and earlier this year I became aware of GridSure who use a pattern embedded in a varying grid of characters, as a one time password. I am not sure why technologies like these latter two have not taken off. They would seem to be potentially more secure than passwords and have lower maintenance costs - the costs of helping users who forget their passwords.
