Are you looking for a step-by-step guide on how to configure a password-less sudo on your Linux system? If so, then you’ve come to the right place. In this Linux tutorial, we will be discussing how to configure a secure password-less sudo on your system.
Sudo is a powerful Linux command that allows users to execute commands as the root user. By default, sudo requires a password every time it’s used, but with a few modifications, you can configure your system to skip the password step and allow users to execute commands without a password.
For the purposes of this guide, we will assume that you are using a Debian-based Linux distribution such as Ubuntu or Linux Mint. With that in mind, let’s begin our tutorial and discuss how to configure a password-less sudo on your Linux system.
At the outset, it’s important to understand that configuring a password-less sudo on your system is not recommended, as it will reduce the security of your system. However, if you are comfortable taking that risk, then read on to learn how to configure a secure password-less sudo on your system.
To begin, you will need to edit the sudoers file. This can be done by opening a terminal window and entering the command “sudo visudo”. This will open up the sudoers file in the nano text editor. Once the file is open, you will need to add the following line at the end of the file:
username ALL=(ALL) NOPASSWD:ALL
Where “username” is the name of the user that you want to be able to execute commands without a password. Once you’ve added the line, save the file and exit the text editor. After that, you will need to run the command “sudo chown root:root /etc/sudoers” to apply the changes.
Now, the user specified in the sudoers file will be able to execute sudo commands without a password. However, this also means that anyone with access to that user account will also have password-less access to sudo commands. This is why it is important to limit access to the user account and make sure that only trusted users have access to it.
This tutorial has provided you with the steps necessary to configure a password-less sudo on your Linux system. However, it is important to remember that this is a security risk and should only be used if you are comfortable taking that risk.

By following the steps outlined in this tutorial, you will be able to configure a password-less sudo on your system. So what are you waiting for? Give it a try and see the results for yourself.
Linux is a powerful, open source operating system used by many individuals, companies, and organizations for a variety of purposes. As a Linux user, you may want to configure your system to allow for password-less sudo access. This tutorial will walk you through the steps of setting up a passwordless sudo user on your Linux system.
Why Configure Password-Less Sudo?
Configuring a passwordless sudo user is beneficial to both you and your system. It allows you to quickly and easily run commands as a privileged user without having to enter a password every time. This can be especially helpful if you are running scripts or programs that require elevated privileges, as you won’t have to keep entering your password.
What You Will Need
In order to configure passwordless sudo, you will need the following:
- A Linux system with root access
- A text editor (such as vi or nano)
- A sudo user account
Step 1: Edit the Sudoers File
The first step in setting up a passwordless sudo user is to edit the sudoers file. This is a file that contains information about who can run what commands as a sudo user. To edit the sudoers file, you will need to use the visudo command. This command will open the sudoers file in a text editor.
Terminal Output
$ sudo visudo
Step 2: Add the User to the Sudoers File
Once you have opened the sudoers file, you will need to add the user to the file. To do this, you will need to add the user’s name to the list of users who can run commands as sudo. This list is located at the end of the file.
Terminal Output
username ALL=(ALL) NOPASSWD:ALL
Step 3: Save the File and Exit
Once you have added the user to the sudoers file, you will need to save the file and exit the text editor. This will ensure that your changes are applied to the system. To save the file and exit the text editor, you will need to press Ctrl+X, followed by Y and Enter.
Terminal Output
Ctrl+X, then Y, then Enter
Step 4: Log Out and Log Back In
Once you have saved the sudoers file, you will need to log out of your system and log back in for the changes to take effect. This will ensure that the new user has sudo access without a password.
Terminal Output
$ logout
Step 5: Test the Configuration
Once you have logged back in, you will want to test the configuration to make sure that it is working properly. To do this, you can attempt to run a privileged command as the new user. If the command runs without prompting for a password, then the configuration has been successful.
Terminal Output
$ sudo apt-get update
Configuring a passwordless sudo user on your Linux system is a simple process that can save you time and effort in the long run. By following the steps outlined in this tutorial, you can easily set up a passwordless sudo user that can quickly and easily run privileged commands on your system. This can be especially helpful if you are running scripts or programs that require elevated privileges, as you won’t have to keep entering your password.
