Wordlist generator based on password cards

Wordlist generator based on password cards

What is a password card?

Password (aka. grid) card is a physical card that allows you to memorize your passwords easier.

The card contains a block of random alphanumeric characters. You just need to choose and memorize a row, a column and a direction to pick a password from the card.

Security

Passwords cards heavily rely on physical security. The card should be kept in your wallet or pocket, far away from watchful eyes around you.

In case the card is lost or recorded with a camera (e.g. CCTV), your password is compromised therefore it should be changed immediately.

Features

Munchkin can generate wordlists from compromised password cards.

This utility generates potential passwords and dumps them onto the screen or into a text file. The list of passwords can be used for brute-force attacks.
