I have looked at other another thread on the matter but in that persons instance they wer able to successfully change it's password, I however have not been able to. I leave the field blank and enter a new password and I get an error that I need to enter the current password in order to make the change. I have managed to change the live session users account type to a regular desktop one because I created another admin account. I can see a potential security risk in having the live session user account present on a persistent USB drive especially. I cannot see the account using the GUI at all when I am logged into my admin account. So I cannot delete it from there. And as I have changed the live session user (refered to from now on as LSU) to a desktop user that doesn't have the ability to admin the system I figured that that would be good enough but I was able to switch back to an admin again while inside the LSU account.
My goal is to delete the LSU account or failing that change the password so that the security flaw is not an issue anymore. I would normally just play around with the terminal trying this that and the other suggestion using an answer to a question that was sorta similar and likely break the USBs ability to function properly then reinstall however I want to not do that this time if at all possible because it takes so dang long to create the persistence partition on the USB key that it's why I don't normally create them. This USB key is for a friend's kid whose HDD has failed and until I can find another one to replace it with (he can't afford much so it has to be a used one).
I am thinking that the best most efficient way to work around this problem would be to use the other account and start breaking things relating only to the LSU's account so that it generates an error that prevents the ability for that account to function properly, however I am a little skittish in attempting to start sudo chopping that account and end up having to start from scratch. I know enough commandline to mess the whole system up as I try to apply previous knowledge of one thing and apply it to another & that doesn't always work out. The last serious screw up I deleted the entire usr\bin folder when I forgot to add the foldername I wanted to delete during a manual uninstall of sublime text 2. Anyway I have rambled on enough sorry about the detritus but not enough to remove it apparently. Thanks for any help
