1. Print the card and store it securely
2. Choose a start position (e.g. 4C) and a direction (horizontal, vertical or diagonal)
3. Read the desired number of characters in the chosen direction
4. When the password reaches the end of the card, it automatically jumps to the other side:
• Horizontal: Jump to next row, from row 12 to row 1
• Vertical: Jump to next column, from column T to column A
• Diagonal: Both coordinates wrap independently
5. The card behaves like an infinite surface - passwords of any length possible!
Important security notes for using password cards:
All generation happens locally in your browser - no data is sent to servers.
