I was changing my administration password to my computer and I must have made a mistake and mis-typed some part of the password because I tried every password I had put on the PC, nothing worked. Is there anyway to wipe the PC (the memory card is a SSD Sandisk 120GB) or recover the administration password? Plus the PC is currently turned off so is there a way I turn It on in a passwordless root or something? Also every time I try the grub boot, when it asks me for a new password I enter it and it says "authentication token manipulation error. What does that mean???? Will I have to wipe the memory or just buy a new one.

I'm working on a Ubuntu system, and my client has completely forgotten his administrative password. He doesn't even remember entering one; however it is there.  I've tried the suggestions on the website, and I have been unsuccessful in deleting the password so that I can download applets required for running some files. Is there a solution?

It never gave me the option to make a password, and now I can't even sign in. I've tried to click the link, but then it takes me to some website that doesn't help me at all!  How do I recover my password?

Possible Duplicate:          I want to change my BIOS setting but when I press F2 it asks for a password and I've forgotten it.  However, if I press enter it just enters the BIOS but most options are greyed out.  Is there any way to reset the BIOS password?  My BIOS is Intel BX97520J and I can start the system which has Windows Server 2008 installed.

Just loaded Ubuntu Server 12.04.2 and all went well. I rebooted the system and up came Ubuntu login:   I tried everything I could think of and pressed Enter. 'Password' appears, but it won't let me type anything. What is my login? I remember being asked to set a password, but not a login name.

I've not been able to save new passwords to my keychain lately.   In addition, I can't view any of my passwords. I'll open Keychain Access, pick a login entry, click the Show Password checkbox, and enter my account password. When I do this, I get an error message:    This is really weird considering my account is an Admin user:    Keychain Access isn't my main password repository so I don't really care if I need to reset it. I tried going into Keychain Access to reset my default keychain.    When I do this I receive the error message:     Like I said, I'm an admin for my computer. There is another admin account that was setup when this computer was imaged, but that account shouldn't own my keychain, right?!  I tried looking for Keychain First Aid but apparently that's been removed.  I'm running 10.12.4.  Any ideas of what's going on and/or how to fix it?

I have accidentally typed my name wrong when I created the administrator account. Although I managed to change the user name at the login screen, I am unable to rename the /home/oldusername to /home/newusername. I tried most of the online tutorials, and it failed.  The code I tried was this:  usermod -l newusername -m -d /home/newusername oldusername   But the output is:  cannot lock /etc/passwd; try again later.   How can I fix the issue and change the folder to newusername and expect all the applications to work as before?

Is it possible to remove a user's password using the net command?  I tried "net user &lt;name&gt; *" and just hitting return twice, but this does not work as expected. Is there any other way to do this? (I'd gladly take non-net commands, as long as they are built-in in XP SP3).  Edit: Seems, I did not make my intention clear. I don't just want to change the password, but remove it completely (so that the user may log in without having to supply a password).  I'm familiar with the "net"-reference and have searched online for several hours, but could not find a hint on how to do this.

I was trying to change my username and also my home directory (/home/username) and my system started to crash. I deleted the passwd file but I had a backup named passwd_bkp. I tried to rename this passwd_bkp as passwd and it did not work. No commands were being executed... I was in a terminal window.   I restarted my system and now I cannot log in. GRUB gives two options: Linux and recovery mode.   I tried to open a sessions as root but it says the filesystem is corrupted. I cannot access my files.  Did I lose all my files?

I Tried to remove the Boot up Bios password in a Fujitsu Lifebook Bios SH530 Model. But it still asking for password on bootup and now may password did not work. Can anybody help me? Here's what I did:   Press F12 on Bootup  Sign in using the old password Go to Security Settings Tab Change the Boot up Password by Typing in the Current Password and leaving the New Password Inputbox Blank. I just press enter 2x. exit the bios screen and save settings &lt;-- The Worst next time I Boot up it still ask for password but my old password did not work. I tried just leaving it blank and press enter but it is Invalid! I tried 3x and wooops a non stop long beepp sounded with SYSTEM DISABLED on screen no Hash code or what so ever.   What did I do Wrong? Do anyone have this experience? What did you do to solve this problem?   PS. I do not know the supervisor password for it.  UPDATE:   It seems the Master Password will only show up on boot before loading windows 7. If will not show up on Bios Settings. I'm currently using this page to decrypt the hash code  My question now is how do you display the Master Password Hash in Bios Setup? If I can get it I can decrypt it and hopefully remove the password.

on one of the boxes I don't control at work I use ssh keys to log in. Our passwords are set to expire after a few months. What happens if I don't reset my password and it expires? will I still be able to login? Does what happens depend on some sshd setting? or some pam setting?

I tried to create a new user account from 'User Accounts' in the System Settings.    First I pressed the Unlock button and the + button.  Then I chose Standard account type and filled account name. Then I pressed Add button and the account is shown there. It didn't asked for any password when the new user account was created.   When I tried to access the new account after a system restart, surprisingly, it asked for a password. Why they asked a password now?

I was wondering if I use my computer running Ubuntu only for browsing while using the guest account on an unpatched PC logging in to any site I browse - will it be possible to steal any passwords typed into the browser or not?   Can e.g. a harmful web site steal my administrator password for the PC or even the WiFi password?

I just installed Ubuntu 12.10 and afterwards, I accidentally set the administrator account password to empty/null. This gave me problems when trying to do administrative tasks in the GUI, so after reading up on askubuntu I used the passwd command to set the password for the account anew.  However, at the login screen when clicking on the account, I'm not asked to enter the password; but, instead, I log in directly as if there is no password set for the account.  When doing administrative tasks in the GUI, I will be asked for a password.  What do I do to be asked for the password at login time?  I did already try, several times, in the User Account settings window to set a new password for the account. That is, in the settings window it does not say "login without a password" for my account and it shows that there is a password set for the account.

I am using a cloned hard drive in attempts to restore some old files.   The cloned drive has 2 users, one with an encrypted home drive, one without. Both are administrators. When I couldn't get into the main user (with the encrypted home directory), I logged in as the 2nd user and changed the password.   It seems that I somehow broke the relationship between the encryption passphrase and the user. I'm pretty sure I have the passphrase. Is there a way to get to the data?
