I installed UBUNTU 12.04 LTS today. I had kept my password as "1317kmb".On restarting and updating it asks for password. when i use the above mentioned password, it does not accepts. I don't know why? How can I reset password. All my enthusiasm of using UBUNTU has been lost by this.

  • You do have an m in your password. Can you try 1317k;b just to check it is not the difference between qwerty and azerty? – don.joey Jun 10 '13 at 9:43

  • If this is a keyboards issues, check the active keyboard on the login screen. – don.joey Jun 10 '13 at 9:45

You may try typing the password on the user name field to make sure that you are actually entering the correct password.


Open a Terminal window or access the prompt from your grub menu (see https://help.ubuntu.com/community/LostPassword) and type in

sudo passwd

Enter your password at the prompt and follow the on-screen instructions

Please Note When you enter your password and confirm it, nothing is displayed on the screen... It's not your keyboard!
