Ubuntu – How to add a Password to User Account if previously it set to “Log In Without Password”

passwordusers

I'm using Ubuntu 11.10 and some time ago I opened User Accounts with Administrator Privilage and I made change as "LOG IN WITHOUT PASSWORD" and now I want to add a password to My User Account. But I can not unlock the user account dialog, because it is asking for password and if it left blank still it's not opening!
Please Help Me to solve My Problem!

Open a terminal, and enter "passwd" ... this will change the password for the current user. If you want to change an other users password, you will need to enter "sudo passwd", because then you need to run passwd with root privileges.

Try sudo usermod -U username to unlock your account.

Ubuntu – set the user account to have no password

You can't do that using the GUI tool, but you can using the terminal.

First, if your user has sudo privileges, you must enable its NOPASSWD option. Otherwise, sudo will ask for a password even when you don't have one, and won't accept an empty password.

To do so, open the sudoers configuration file with sudo visudo, and add the following line to the file, replacing david with your username:
```
david ALL=(ALL) NOPASSWD:ALL
```
Close the editor to apply the changes, and test the effect on sudo in a new terminal.
Delete the password for your user by running this command:
```
sudo passwd -d `whoami`
```

If you ever get prompted for a password, just type enter and it should work. I've tested this answer with LightDM, the lock screen, sudo, gksu and it works, but there's one more step to get it to work with pkexec (thanks muru).
