I recently used @Harsh 's mkusb instructions to successfully create an Ubuntu 18.04 live USB with persistence greater than 4 GB. The default user is
Ubuntu and the default password is
, that is to say blank (just hit enter).
Can I run the
sudo passwd Ubuntu command and add an actual password to this live USB system? I want a password required on boot and on the lock screen as well. I don't know what issues this would present, if any. I do understand somebody could still mount my live USB system on another Linux machine, and have access to my files. My password requirement is a very low level of defense, that I'm comfortable with, and want.
Alternatively, could I simply delete the
Ubuntu user, and add myself
jason as the only user, create a password for
jason, and be done with it?
