Ubuntu Ahtorizations?

Do not. Repeat, DO NOT. If you want to turn off the password, go back to XP.

Linux took over the whole security scheme from Unix, which of course evolved at Universities and large corporations where not everybody who had a password was always trustworthy. Case in point, the first worm ran on Unix computers. Windows evolved on little stand-alone boxes which had one user and couldn't connect with each other very well. Until recently everything in Windows ran in administrative space and Users and visitors had free access to everything. That is how the botnets and the other forms of monetized malware got so big -- that and Microsoft's stupid attitude that some vendors be more trustworthy than others in an environment where it is still incredibly easy to lie to these stupid computers about who you are.

With *nix there is administrative space and there is user space. User space is where most applications run, where they do not have the right to change any of the settings on your computer. Of course you do, but you either need to be running things as the administrator (root) or you need root permission to be running that command in administrative space. A Slackware group I used to belong to had the catchphrase "If you surf the net as root you may as well be running Windoze." BSD came up with the sudo program which is the one which lets you run one command as root, and when Shuttleworth and his elves decided to make Debian safe for n00bies he disabled the root account entirely and forced you to use sudo so you aren't running an account that hackers can compromise.

I'm one of those people who thinks that people who say Linux never gets viruses are idiots. I run ClamAV and check for root kits regularly. I'm not that adept but I'm well aware that if I am compromised (and catch it) I am simply more likely to know the name of the person who did it than you are.

I run Debian, not Ubuntu, so I have a fully functional root account but I almost NEVER run it unless my computer IS NOT CONNECTED TO ANY NETWORK (the wires have been removed). I do know a workaround wherebye you can get a terminal prompt with root permission, but obviously I am not prepared to give it to you because I'm afraid you will do something like get infected and provide malware writers with technical information which will make it easier to recruit MY machines into a botnet.

Practice safe computing. If you want to customize anything, run sudo, which at least the GUIs of your programs calls for you. Or go back to Windoze.
