My friend Brent and his team recently launched Valt. When I was in his Comp Sci class in undergrad I remember him showing us an early demo.
It turns out, people are really good at remembering images they've seen before (smells even more so). People are much better at this than remembering passwords and even pass phrases. Valt, much like 1pass, stores all of your passwords stored behind a pseudo-password of memorable images. Incredibly hard to guess, nobody can steal it.
What do you all think of this concept? Feel free to try it out, but looking for some discussion on the idea in general.
