This question already has an answer here:

I know this has probably been asked before, but I just installed Ubuntu last night and all the replies I read I honestly couldn't understand anything :p

I need to make some changes, and all of them seem to use sudo. When I formatted the pc and installed Ubuntu, it asked me for a password and didn't give me a chance, to have no password. So I then went on and removed the password completely, when the pc was on and the installation was complete.

I then had to use sudo as I said for a couple things, but it asked for a password. I tried to put the old one, I tried to leave it blank, I also typed NOPASSWD, and other variations of that. Nothing worked. I have rebooted the pc also in between of that so for now I have no idea what to do.

Please help, it's really frustrating :(

Edit: I am not looking to reset or restore any password. All I want is to not have a password set at all, and to not be asked for one by sudo, when there is none.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • I wasn't aware that the issue is losing the password? I haven't lost it I just removed it completely? Is this a bug? – Gogo Jan 20 '18 at 12:09
  • I did remove the password. I went into the user profile/ account, and removed it completely. Now it says "none". Sudo is still asking for password though. – Gogo Jan 20 '18 at 13:03

From the title :

You can edit your sudoers file like:

sudo visudo

And add the following entry, replace user with your username, for example gogo:


Press ESC then :wq to save it. Then re-login.

However this is consider as a very bad security approach. Note that each active non-root account needs to have a password.


Abbreviation sudo means super user do. Certain binaries are executable only from privileged account - root. Normal user accounts can escalate this by configuring their account in the sudoers file.

If you are asking for restoring the password, refer to the mentioned links in the comments.

  • This pc is in our living room and will be used only by my parents (that are 100% irrelevant with technology, to watch movies. Therefore having a password is completely useless in this case, and most of the time annoying when I'm trying to do things quickly. I never asked for restoring any password I'm not sure why my post is marked this way. But I will try what you said a bit later and let you know how it went! Thanks – Gogo Jan 20 '18 at 12:44
  • If then so - please follow the instructions from my answer. – fugitive Jan 20 '18 at 12:48
  • Okay I will do that later and update this post thanks a lot! – Gogo Jan 20 '18 at 13:04
  • Now I've read the question more closely sorry, before applying my suggestion, you will need to apply @Matteo S. answer first probably if you don't you know your root password as well. If need more help, let me know. – fugitive Jan 20 '18 at 13:08
  • What is a root password and when was that set? The only password I set was the profile password, that I have removed. – Gogo Jan 20 '18 at 13:18
