Description
If you need to remember dozens of passwords without having to remember all of them then with password cards you can have it. Each password card is a set of grids with random letters and digits on it has 8 rows which have different colors, columns mapped to different symbols. Everything needed is to remember a combination of a symbol and a color or an index of row, then compose the letters and digits of your passwords from there.

PWC
If you need to remember dozens of passwords without having to remember all of them then with password cards you can have it. Each password card is a set of grids with random letters and digits on it has 8 rows which have different colors, columns mapped to different symbols. Everything needed is to remember a combination of a symbol and a color or an index of row, then compose the letters and digits of your passwords from there.
Build
$ go build -o pwc
Installation
$ go get -u github.com/imanhodjaev/pwc
CLI Use
$ ./pwc classic -h
Generate classic password card
Usage:
cmd classic [flags]
Flags:
-e, --encrypted string When given will encrypt generated card and write to file (default "card.aes")
-h, --help help for classic
-d, --include-digits Rows 5-8 will be digits only
-s, --include-symbols With regular a-zA-Z include @#$%&*<>?€+{}[]()/\
-o, --output string Output file (default "card.jpg")
-p, --print-passphrase Prints passphrase in the console
Example card
How it works
$ ./pwc explain
Alphabet
Header symbols: ■□▲△○●★☂☀☁☹☺♠♣♥♦♫€¥£$!?¡¿⊙◐◩�
Numbers: 0123456789
Alphanumeric: 0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ
Alphanumeric and symbols: 0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ@#$%!&(MISSING)*<>?€+{}[]()/\
Algorithm
1. Render the first row with shuffled "■□▲△○●★☂☀☁☹☺♠♣♥♦♫€¥£$!?¡¿⊙◐◩�",
2. Iterate over the rest of the rows and for each randomly selected letter we shuffle the entire alphabet
a. If the card should include symbols then
use the alphanumeric and symbols alphabet for every even character
and use the alphanumeric alphabet for the odd columns,
b. If the card should have a digits area then
use the numeric alphabet for the lower half of the rows 5-8.
Row colors
White #ffffff, Gray #c0c0c0, Red #ffc0c0, Green #c0ffc0, Yellow #ffffc0, Blue #c0c0ff, Magenta #ffc0ff, Cyan #c0ffff
