Jupyter password?

What is the password?
jupyter@GoPiGo:~ $ sudo shutdown now
[sudo] password for jupyter:
Sorry, try again.
[sudo] password for jupyter:

ps. great software - well done!!!

the password is not needed for a shutdown. Please use the press button on the robot itself. it will do an actual shutdown of the Pi after having taking care of the gopigo board properly .

And thanks for the feedback on DexterOs !
