Linux mint forgot password

It’s really a life saver. It’s a little bit dated, but thanks to the helpful comments from eiger3970 and vonoctra, it still has relevance. Thank you for sharing and saving the day.

I tried this on my Linux Mint 12, however it it doesn’t work.
Boots into a black screen and have to manually reboot and then shows regular welcome screen.

I tried:
In Linux Mint 12, the line to edit begins with «linux» and not «kernel»

Follow steps 1 through 4 above.
In step 5, navigate to the end of this line:

linux /boot/vmlinuz-3.0.0-12-generic root=UUID=[letters and numbers]\[letters and numbers] ro quiet splash vt.handoff=7

ro quiet splash vt.handoff=7

linux /boot/vmlinuz-3.0.0-12-generic root=UUID=[letters and numbers]\[letters and numbers] rw init=/bin/bash

Press Ctrl-x or F10 to boot with these options
Follow steps 8 through 11 in Alexio’s tutorial as normal

I want to try this on my Linux Mint 14 but for some reason it wont go to the GRUB menu when I boot holding shift. I hold shift, turn it on, keep holding shift, and it just boots right up to the desktop.

Excellent! Worked on Linux Mint 13.

how about linux mint 14? does it work?

I think you should update the article according to bugmenot’s comment. As of Linux Mint 14 RC (Nadia), bugmenot’s comment is correct.
Thank you, Alexio and bugmenot.

What about Linux 9? Am a TOTAL Linux (but not computer) newb.
Installed Linux (Isadora, it says) on HP Omnibook 6000.
Made it as simple as possible: I know my user name, I know my password.
I enter them in their boxes as they appear/are requested
(first one, then the other, but both never appear on the same screen. Also tried UC and LC letters, or first letter UC)
Box(es) return(s) for me to fill again -and again — and again — and again. (ad nauseum) 😡
NOTHING else happens, not even an error msg. . . .
Have rebooted -several times.
Have reinstalled and rebooted.
Same result. 👿

Attempted the fix but got same result as djbyardie.

Ready to go back to Ubuntu, no matter how slow it was (and will be again) because at least it WORKED and made sense!
Would be a shame to quit now, but this. is. bloody. annoying . . .
The only good news is that this is a new install and I have nothing to lose, except time and my temper.
Help!

Did not work on Linux Mint 13 even with @bugmenot clarification. Hit Ctrl=X or F10 screen went blank and nothing. I see a reinstall in my future. But it shows me how much more secure Linux is.

Lost Password¶

If your disk is encrypted it is not possible to reset the password. If your home directory is encrypted changing your login password won’t help. Unless you made a backup of your encryption passphrase it is not possible to access the files.

If you forgot your password, and neither your partition nor your home directory are encrypted, there are two ways to reset it:

Recovery Mode¶

Boot up the computer, and after the BIOS screen, hold down the left Shift key to force the boot menu to show up:

On some computers you might need to press the Escape key instead.

Select the second entry from the top, the one that starts with Advanced options .

Then on the next screen, select the second entry again, the one that ends with (recovery mode) .

Linux Mint will then starts in recovery mode and present this menu:

Select root to get a root prompt and press Enter.

Use the passwd command to reset your password. Say your username is joe , type:

Chroot from Live ISO¶

Boot up the computer from the live ISO.

Once in the live session launch Gparted from the applications menu.

Identify your Linux Mint partition (usually a large ext4 partition). In the example above the Linux Mint partition is /dev/sda5 .

Open a terminal and type the following commands:

mkdir hdd sudo mount /dev/sda5 hdd sudo chroot hdd mount -o remount,rw / passwd joe

Replace /dev/sda5 with your Mint partition and joe with your username.

Forgotten username¶

If you can’t remember your username type the following command, either in the chroot prompt or the recovery mode prompt:

This command lists the directories in /home which usually corresponds to the list of usernames on the OS.

On the first highlighted option, press ‘e’ on the keyboard to edit the grub parameters. You should get the screen shown below.

Next, scroll down using the arrow down cursor key until you get to the line beginning with ‘linux’ . Navigate until you get to the ro quiet splash section and add rw init=/bin/bash .

Then press ctrl + x or hit F10 to boot into a single-user mode as shown below.

How to Reset the Linux Mint Password

A password is a term that is used to obtain an access to something or someone. A group of characters are used to enter a level in a game or log into a computer network. You must generate a complicated password whenever you use a system. A password is the fundamental authentication of any device including computers, iPads, and other electronic devices. There are numerous methods to reset the passwords which are frequently forgotten by the users of devices or systems. If you forget your Linux password, it’s not a major deal because Linux offers several options to reset or change the password which is what we’re going to do in this article. We’ll demonstrate how to utilize the boot menu or the commands and command line interface to reset the root or the user passwords on Linux Mint.

How to Reset the Linux Mint Root Password

In this example, we’ll demonstrate one of the simplest ways to change or reset the passwords on Linux Mint. Linux offers us a variety of alternative options to reset the root or user password. The user root passwords are commonly forgotten. It commonly occurs, particularly if you haven’t logged in as the root user in a while. But don’t worry because we’ll provide you with the simplest method to reset your password again.

Let’s begin its practical implementation. First, we start the Linux Mint system and then restart it by clicking the “Start” button to open the menu. Next, we click the “Power” button at the bottom-left corner to access its choices.

Now, after pressing the power button, a session with the “suspend,” “restart,” “cancel,” and “shutdown” buttons will appear on the screen. Since we want to restart our system, we press the restart button.

To access the “GNU GRUB” boot menu, you must now press the left “shift” button at the beginning of the boot press. You can press “ESC” on the keyboard at the GNU GRUB prompt if it cannot be enabled by holding down the shift key. The following image shows how the GRUB menu appears on the screen after holding down the shift key. Additionally, the window displays the GNU GRUB version, which is “2.06,” as well as its entries:

To edit the commands, hit “e” at the default option in the following step. The edit mode, which you can see in the following image, is entered when we press the “e” key from the keyboard. You may now edit the commands here.

After switching to edit mode, we use the keyboard’s arrow keys to navigate to the end of the line that begins with Linux. The following graphic demonstrates that we obtained the line that originates from Linux:

Now, we type the command at the end of this Linux line. First, we type “rw”. Then, we type “init” after a space. The term “init” refers to initialization. Simply said, init’s task is to create the processes from the scripts that are stored in the /etc/inittab configuration file which is used by the initialization system. After “init”, we type the equals symbol “=” and then the “/bin/bash”.

After entering the command, you must now boot your computer by pressing the “f10” key or “Ctrl-x.” After pressing the key, as shown in the following screenshot, we are now inside the root shell.

The “passwd root” command is entered to update the root password. On Linux, the “passwd” command is employed to modify the user account passwords. A common user is only able to modify their account’s password. Any user account’s password can be changed by a root.

As noted in the following illustration, the root shell now prompts you to enter your new password after you execute the previous command. For instance, if we want to use “123” as the password for our Linux system, we type “123” and then press the enter key. The shell subsequently requests us to input a new password again. We type “123” once more before hitting the enter key.

Our root password for Linux is now reset after pressing the enter key which prompt the “password updated successfully” statement to be displayed on the window as an output.

Now that we have an access to the root shell, we can also change the user password. In this section, we will do just that. But to do so, we must enter the general username for our system. In this case, the user name for our system is “Omar”. Now, we enter the password command, “passwd”, followed by the user’s name, “Omar”.

After running this command, the shell prompts you to create a new password. Enter the new password using the same instructions as in the preceding part, then hit “Enter”. The next time it prompts you to enter a new password, simply type it in again and hit “Enter”.

Now that the password is updated, the output is presented along with the “password updated successfully” message.

Changing the User or Root Password Through a Command on the Terminal

We’ll explain a different method of changing the password on Linux in this section. To change or reset the password, we use a command on the terminal. First, open the terminal. Then, input the password command, which is “passwd”, into the terminal screen.

The system prompts for the current password after running this command, so we entered it. For instance, if the current password is “123,” we must enter it and then press the enter key.

After that, we are prompted to provide a new password. We type it in here before pressing the Enter key. The new password is then required to be entered a second time.

The update of password notification will appear on the screen as seen in the image below once the new password and the password you typed again have successfully been matched.

Now that we have another user with the name “guest”, we use the sudo command in the following section to change their password. To do this, type the following commands into the “sudo” terminal, “passwd”, and “username”, which is “guest.” In our case, our other user is called “guest”. So, we type “guest” after typing “passwd”.

Therefore, when we run this command, it asks to input a new password. Here, we add the new password as we did in the previous step. After entering, it asks us to retype the password. If we do so, and the new password and the retyped password match, the password is updated.

The changed password message is now visible on the terminal.

Conclusion

We covered how to reset or modify the Linux Mint password in this article. We used two distinct approaches to password change. First, we reset the root password or modified the user passwords using the “GNU GRUB” boot menu. In the second approach, we updated the password by executing the “passwd” command in the Linux Mint terminal window. We also changed the password for another user using the sudo command.
