This demo on Ubuntu Linux shows how to configure sudo so the user does not have to type in their password to run sudo commands. The simple demo uses visudo available on most popular Linux distributions so this technique will work on many distributions. Ubuntu is not special in this case. Other Linux distributions where this was tested include Debian Linux and Kali Linux, but should work similarly on RedHat distributions like CentOS.
The password feature on sudo is there by default for safety and security reasons, so it is assumed anyone watching this video understands these security concerns and the consequences of not having password protection on the sudo command.
Welcome to our comprehensive guide on how to configure and use the "sudo" command in Linux without requiring a password entry. In this tutorial, we'll walk you through the steps to grant users passwordless sudo access, simplifying and streamlining your Linux system administration tasks.
Video Highlights:
Introduction to passwordless sudo in Linux
Understanding the "sudo" command and its significance
Safely editing the sudoers file
Enabling passwordless sudo access for specific users
Testing passwordless sudo privileges
Best practices for maintaining security
By the end of this video, you'll be equipped with the knowledge and skills to configure your Linux system to allow specific users to run privileged commands without the need to enter a password each time. This can be incredibly useful for automation, scripting, and managing your Linux server efficiently.

Hi. I have an Oracle Linux server that’s joined to an Active Directory domain. I want to grant a specific Active Directory group the ability to switch to the oracle user without entering a password using the su - oracle command. How can I achieve this? Could you provide an example for configuring the sudoers file correctly to allow members of this group to execute the command without a password prompt?
Thank you for your guidance.
I am not able to write password in my terminal .

Ya same help me pls
Yes
Did you giys figure it oir its been 2 years 😂
It works but you have to add it to the very bottom of the file. It won't work if you add it anywhere else. I'd imagine it has something to do with the #includedir but then again I'm new to this whole GNU/Linux thing. So far I configured my server's firewall, public key access, and disabled root account.
Thank you so much. Your comment saved a lot of my time.
What is password of sudo I don't know what you mean??
same here any fix
thanks it took me 3 hours to fix this
Video was good but I have a query. I locked a file using "chmod 700" and changed its ownership to "root:root". So, as a root, when I open it for the first time it asks for the password. That's what I want. However, when I open it using "open as root" it won't ask me the password(THE SECOND TIME). Let's say I have a private file and I just had a glance and closed it. Some random user can open it as stated in aforementioned way. My question is how to authenticate everytime?
Based on the way the question is asked, you might encrypt the file with zip -e or other encryption. This will protect the file from being read and also require a password everytime you want to decrypt it.
Hello i have a question when my screen goes off and i wake it up by moving the mouse it keeps asking me for a password. How can i stop that. This way you are doing it will work?
Not really. You want to adjust your screenlock settings for that issue.
Thank you so much and it works!
Excellent (and short) video
I am so safe now i can do absolutely nothing in my new vanessa mint my password will not work and the terminal does not accept anything at all in it not even sudo
Thanks to you, I, a new linux user can now su without password. I am very gratefull sir!
Is sudo password same as your login password to login at login page?
Nevermind the question. Duh....it is, the problem was I wasn't in sudoers file, and all I had to is add my user account to sudoers file in gno nano page window, plus add the following line from tutorial so I don't have to have to enter a password every time.
I fixed my issue thanks to your video.
Thank you!!!
sudo visudo does not run in vanessa linux mint . i am forced to lose everything AGAIN. Linux getting to be a bitch
Why is using a password saver
