If you haven't previously changed the linaro users password the default is "linaro", so you can reset the password by issuing the following command.
And enter the old password and then repeat the new password to set your new password.
If you do not currently know the password (but have been automatically logged in) you can reset the password via
sudo passwd linaro
This will allow you to reset the password without knowing the existing password.Tags: iteaduino, iteaduino plus, linaro, password, reset
