Wallet: The most secure, elegant, and easy way to store and organize your passwords, serial numbers, credit cards, and more I noticed that Yojimbo has this sort of function built in, which seemed strange to me at first. Maybe it makes sense to bundle that into an overall knowledge/personal information management application. But maybe it makes more sense to have a small app dedicated to it. That's what wallet is, and I guess I'll download it and find out!
