Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I have a system with two accounts. The primary (and administrator) account automatically logs in at boot time and is used 95% of the time. On occasion I need to logout and switch to a secondary account dedicated to part time work which is set to log in without a password (just click login). When I log out of that account I would like to log back into the other without a password but I don't see any way to set that as an option in the "Users and Accounts".

I know how to get disable the password when the screen goes to sleep and I want to keep the password intact because it seems like it is necessary for administrative purposes. Having something that could easily be reversed would also be a plus (in other words just re-enable the password for login).

This is marked as a duplicate, but that question does not answer my specifics and the methods referenced do not show up in my stock 13.04 install. I have placed an answer below that did fit the bill.

Different question. I want to maintain the password just not have to enter it at the login screen. I actually used an answer that was deleted and it worked fine which I may repost unless there is a really good reason not to?? gpasswd -a username nopasswdlogin –  Dennis May 29 '13 at 17:25
    
Take a look at my answer Here. –  Mitch May 29 '13 at 19:02
    
@Mitch: That appears (am I mistaken?) to remove the password which I don't want to do, and only have one admin account. You have much more knowledge than I do in such matters so I'll ask, the gpasswd method seems to work fine. Is there a danger involved that I don't know about? –  Dennis May 29 '13 at 19:58
    
None that I can see. –  Mitch May 29 '13 at 20:09

So you wanted to remove the password of your primary account? I don't know if this will work but try this.

Open your terminal and type this:

sudo passwd -d *username*

Ok this is what I came up with. Logins are without password entry, just click the "Log In" button. Password is preserved and works fine whenever prompted. I haven't tried to reverse it but can't see any reason that wouldn't work.

sudo gpasswd -a <USERNAME> nopasswdlogin

In all fairness this answer was posted earlier but deleted. I don't remember by who but I'm glad I saw it because it is spot on.

To re-enable the password query it would be

sudo gpasswd -d <USERNAME> nopasswdlogin
