cough Allowing a user to sudo without a password cough. UNSECURE! You should not do this. – The Lord of Time Jul 26 '12 at 16:01

You can do this, but it breaks the security model. Are you absolutely sure you want to do this? – Paddy Landau Jul 26 '12 at 16:26

I can understand wanting to do this on a computer, say at home in a secure situation. Security forces a "good" password, which usually means long and harder to type. Trouble is, we have to type it in VERY regularly and it gets to be tiresome. I am not advocating against security, but, especially in the home situation, it may well be desirable to do this. – Jazz Jul 26 '12 at 22:44

This is a very bad idea. What I did was set a differn't password for root privlidges/root, which was easier to enter, but it wasn't very easy to setup. (I don't do this anymore) – user72421 Jul 27 '12 at 5:58

To say this "breaks the security model" is rather extreme. sudo is designed to facilitate passwordless operation easily and even has ready-to-go commented configuration lines in /etc/sudoers to allow a whole group of users to run any command as root without being prompted for a password. There are some adverse security implications of doing this--any program can perform actions as root without you being notified!--but an actual attacker, with the ability to run programs as (non-root) you, can already capture your password as you enter it for sudo (and then run sudo with it). – Eliah Kagan Jul 27 '12 at 17:43

I believe the correct is:

gandalf ALL=(ALL) NOPASSWD: ALL

Put it in the end of the file

I use the sudo group and have:

%sudo ALL=NOPASSWD: ALL
