How to manage VPS users?

In all Linux/Unix-based systems you can create a new user in such a way:

Run Terminal under your superadmin and type 

useradd -m USERNAME , where

-m - optional flag, creating a folder for this user (not needed for certain cervices)
USERNAME - name of the user you want to create

Then you should set a password for this user. Type the following:

passwd USERNAME , and press Enter

You will be requested to enter a password and re-enter it for confirmation. We recommend using strong passwords - with upper and lower case letters, numbers and special symbols.

You can also specify a group this user will be put into:

usermod -G group1,group2,groupN USERNAME

or

vigr -g , where

-G - flag putting a user into certain group or several groups at once
