Today, the security of passwords is very important and very strong passwords are complicated to remember. Tokenino, written in python, generates strong passwords composed by letters(Upper, down case), numbers and special characters. After the random generation, it uploads these passwords on the Arduino micro. The user can require the password by pressing on of buttons on the Arduino.
Man Output of Tokenino:

python tokenino.py -h

I hope this tool may be useful for the community because I use it to decrypt every day my LVM linux partition.
