A PasswordCard is a credit card-sized card you keep in your wallet, which lets you pick very secure passwords for all your websites, without having to remember them. You just keep them with you, and even if your wallet does get stolen, the thief will still not know your actual passwords.

Your PasswordCard has a unique grid of random letters and digits on it. The rows have different colors, and the columns different symbols. All you do is remember a combination of a symbol and a color, and then read the letters and digits from there. It couldn't be simpler!

It would take about 154 nonillion years for a desktop PC to crack your password.
