Click here to Use Password Matrix
Here you find the Documentation
"ALX Password Matrix" can be used to hide a password from people not knowing the scheme ("path") to reassemble the password. It shows a 7x7 matrix containing random characters. Your password is hidden in the matrix and can be reassembled only by your brain, knowing the fields to pick one after another. An attacker will not be able to guess the character order and a brute force attack will be costly, depending on the character types used.
The idea is to store such matrixes in a password manager rather than the plaintext passwords. This way an attacker cracking the password depot does not have immediate access to all stored passwords.
