2 to 3 rolls per character

First roll for the row. Then roll for the digit. My first two rolls were 6 and 1 so I get 5. My second roll was 2, 4, and 4.

2 is the row, 4 is the letter J, and I rolled even so I made it uppercase.

1 : A B C D E F
2 : G H I J K L
3 : M N O P Q R
4 : S T U V W X
5 : Y Z 1 2 3 4
6 : 5 6 7 8 9 0

Optional

Roll odd for lowercase and even for uppercase is totally optional.

I did a test and generated this password:
