• open terminal. Type grub and press enter. The prompt would change to something like ‘grub>’.
• Enter md5crypt at the GRUB prompt. Type in the password when prompted for and press enter. The command will return you password encrypted as an md5 hash.

• Now we need to edit the /boot/grub/menu.lst file. in case of redhat use /boot/grub.conf.

• Enter the line password  --md5 before the line that reads: “BEGIN AUTOMAGIC KERNEL LIST”  you can write it anywhere.
• If you save the file at this moment without any further edits you would have locked down interactive editing in GRUB. The administrator or in this case you would have to press ‘p’ key and enter the correct password to access these advanced options.
• If in addition you want to lock down specific menu entries, you should add the word lock all by itself on a separate line just after the title specification for each entry in the menu.

• The next time anyone tries to select the locked menu entry he/she will be required to enter a password before he/she can boot into the corresponding operating system, and that is so cool....
• To lock the recovery mode entries it is best to change the line lockalternative=false tolockalternative=true. This will lock down all future recovery mode entries as well even if you update the kernel

Password can be reset in the Ubuntu very easily using the recovery mode. I have seen many people who are rebooting or reinstalling the entire system after they forgot their Ubuntu password.

Do not feel  scare in the process as you have to face the black screen. It’s the safest way and is not harmful at all. You can quickly reset the password without any harm following these simple steps.  I would like to apology for bad screenshot which is done by digital camera

Step 3: Now, the real password resetting process starts from here. Type:

sync

reboot -f

The password reset process is successful. Login with your new password and enjoy.
After logging in the screen “Enter password to unlock your login keyring” might appear. To make it disappear you need to type your old password which you don’t remember.  So, change your password again by following the same process.
