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.
A very cute idea, well implemented.
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 couldnโt be simpler!
A chain is only as strong as its weakest link. Itโs 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.
Where do you keep your KeepAss master password?
In my head. If you use a long passphrase, itโs easy to remember, easy to type, and secure.
The pregenerated book of codes is used since ancient times and it is interesting, but I would much prefer to educate people to use passphases instead.
And everybody has a phone with them at all times, you can have Keepass on it. It doesnโt use the cloud, itโs local, and if you need to sync the password database file automatically with your PC itโs safe to keep it in the cloud, itโs encrypted and only decrypted locally. But I myself use a self-hosted instance of Nextcloud.
