The Problem & Solution

Passwords get hacked, password apps leak online, and paper notes get lost.
How do I remember the password for this place?
What if the password app is reset or the device is unavailable?

The solution is simple: use a physical plastic card as a reminder of all your passwords

  • Generate invulnerable passwords using a plastic key card.

  • Store imposed passwords (bank, work) as a zigzag line — even if stolen, the thief won't understand how to use them.

    Password storage example 1

    put a transparent card over the line

    Password storage example 2

    keep the hint cards away from the zigzag

    Password storage example 3

    no convoluted apps, easy to use

1

Transfer the password to paper as a zigzag line

If you have been given a complex password, then create a zigzag line on the hint card. Transfer it to paper using carbon paper or screen light. It is also convenient to use sticky transparent notes for this. Don't forget to draw the card edge markers.

2

Save the key zigzag line

Save the key zigzag line. Can be stored near the password entry point or in a password book. Important to keep away from the transparent card.

3

Place a transparent card over the zigzag line

Place the transparent map over the zigzag line. Match the markers to the card borders. Read the password from the nodes of the line

Security tip: Even if your card is stolen, without knowing your algorithm it's useless!
