Distruptive technologies ocassionally come along which can make a big difference in computing. Something in the early days which I heard about last week was the SQRL authentication proposal by Steve Gibson. This proposal aims to address the extremely big problem of user and password authentication across the internet. This is a huge and annoying problem for all internet users - you must try to come up with secure passwords, whilst giving passwords to many different parties, some of who you can trust, and some of whom you can’t.
