So it's like "Simon says" ?

first one needs to have one of the Linux variants installed
and not mind the possible security issues related to using it
root = god
root is almighty
most long time linux users use one of the two " su" or " su -" commands to become root ( temporally ) and dislike sudo with a passion

but sudo ( and it's variants) let a NORMAL user do things as root WITHOUT NEEDING roots PASSWORD

can be used by IT to let one employe do "some" things that root can do without giving FULL root access to that employe

can be good for letting the kids install programs in ONLY certain places BUT not allow them FULL control over the computer
but it needs to be set up CORRECTLY otherwise it defeats the purpose

Its like getting access to the boss' email and ordering others around. You are not the boss but get stuff going

sudo on linux does ask you for a password for authentication?

sudo on linux does ask you for a password for authentication?

it uses the users password and NOT THE root password
Ubuntu ( and some others ) just have very low password security and auto sets "sudo" ,they try to be like Microsoft .
the first normal user( at install) and the root passwords are the same unless they are reset ( witch is a very good idea to do )

not all distros do this , just the ones that want to "act" like MS )

the root password SHOULD be different than the first normal user
root should be a very strong password
and the everyday account password - easy to remember
