How to remove password for root (Ubuntu)

Posted on: November 3, 2010

1. sudo -s

2. vi /etc/shadow

3. remove second column (between colons)

then root does not have a password and no one can log in as root, for security reasons.

why this is needed?

I try to change the default settings for the printer to print double sided. Btw, it is called flip on the long edge🙂 But when i apply my changes, it always asks for an authentication for root. So i have to sudo and give root a passwd and then type it in the authentication box. Later on, after confirming that the default printer setting is double-sided, I delete the password for root.
