The only reason for (consumer) passwords you have to remember is lack of an accepted good universal id in general. Here in Sweden it's provided by the banks and has a 94% share of smartphone users, if you look east you have other bigger markets with similar stats. Most passwords already have disappeared or are disappearing, the laggard cases will catch up too, I'd love a similar one for my "work persona".
