Welcome to RainbowCards

What is this website about?

You have lots of website/bank/email/whatever accounts in all sort of systems, each of whom wants you to pick a secure password obeying a different ruleset. Most people find pretty hard to remember one secure password that consists of a random string of letters and numbers, let alone lots of them!

Too many people circumvent this fact by using simple, easy to remember (and easy to guess) passwords, or even use the same password everywhere! The most adventorous ones will have a set of mid-security passwords that will be arbitrarily chosen or combined, but that's about it. In these days of identity theft, that is a very bad idea!

So, what are Rainbow Cards?

A RainbowCard is a credit card/passport-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.

How does it work?

Your RainbowCard has a unique grid of random letters and digits on it. The rows have different colors, and both columns and rows have different customizable labels. All you do is remember a combination of column/row or column/color, and then read the letters and digits from there. It couldn't be simpler!

You can optionally change labeling and colors used to generate your card, which allows you to develop unique remembering techniques and gives your card a more personal look!

Weren't we supposed to not write down our passwords?

A chain is only as strong as its weakest link. It's far safer to pick secure passwords and write them down, than it is to remember simple and easy to guess passwords. You already protect your wallet very well, and even if it does get stolen the thief will still not know which of the many thousands of possibilities on the card is your password.
