[SOLVED] Passwordless Login

Hello,

How do I make user accounts passwordless?  Or perhaps blank?

Thanks.

Re: [SOLVED] Passwordless Login

You should read the manual... (man passwd), what you're looking for is

passwd -d <username>

I've tried this but now I can't login to Gnome.

What you want is probably auto-login. GDM lets you automatically log in given user on boot, bypassing the password.

The issue is - there's two users on this particular machine.

Add the line "PasswordRequired=false" to /etc/gdm/custom.conf under the [security] section.  I'm not using gdm at the moment, so I can't test it, but that should do the trick.

This doesn't appear to have any affect.  I added a new user "test" with no password and couldn't login.

Sorry then, I didn't know you were talking about a login manager.. You can restore the previous state by running "passwd <username>".

Re: [SOLVED] Passwordless Login

Hmm.. I guess I missed that part with the two users.

Re: [SOLVED] Passwordless Login

Not so long ago, I found a solution. Not pretty, but works:
Edit /etc/shadow file, find a line responsible for an account you want to alter and replace encrypted password with following string: U6aMy0wojraho
For example, change:

username:$1$5x0jrV/s$9zI4fnuGfdgrz=Iz/oK99oBo:13727:0:99999:7:::

to:

username:U6aMy0wojraho:13727:0:99999:7:::

Works for me - GDM with passwordless guest gnome desktop.
All credits go to aysiu at http://ubuntuforums.org/showthread.php?t=513820 where I've found this trick.

Good Luck

Re: [SOLVED] Passwordless Login

Ok, but what about sudo ? I still want to enter my password when changing some system settings.
It's something concerned PAM to let enter Gnome or KDE without entering password (even if it is not blank)
How this can be done in Arch ?
