The most effective method try out if you have fail to remember the root password

As a Linux user, you may have come across situations where you have forgotten your root password. Losing your root password can be frustrating and can prevent you from accessing your system. However, there are several ways to change the root password in Linux, and we'll explore them in this article.

Before we dive into the ways to change the root password, let's discuss what the root password is and its importance.

The root user is the superuser or administrator account in Linux, with full access to all commands and files on the system. The root password is the password assigned to this account, and it's critical to keep it secure to prevent unauthorized access to your system.

Now, let's look at the possible ways to change the root password in Linux.

1. Use the single-user mode:

Single-user mode is a mode that allows you to boot the system with administrative privileges, without starting all the services and daemons. This mode is useful when you need to perform administrative tasks, such as changing the root password.

To boot into single-user mode, you need to perform the following steps:

• Reboot your system and access the GRUB boot loader menu.
• Select the Linux kernel you want to boot and press the 'e' key.
• Find the line that starts with "linux" and append 'init=/bin/bash' at the end of the line.
• Press 'Ctrl-x' or 'F10' to boot into single-user mode.
• Once the system is booted, type 'passwd' to change the root password.

2. Use a Live CD or USB:

If you don't have access to single-user mode, you can use a Live CD or USB to change the root password. A Live CD or USB is a bootable media that contains a complete Linux operating system that can be run directly from the media without installing it on the hard drive.

To change the root password using a Live CD or USB, follow these steps:

• Boot your system with the Live CD or USB.
• Once the system is booted, open a terminal and type 'lsblk' to list the available disk partitions.
• Identify the partition where your Linux installation is located.
• Mount the partition using the 'mount' command.
• Use the 'chroot' command to change the root directory to the mounted partition.
• Once you're in the chroot environment, type 'passwd' to change the root password.

3. Reset the password using GRUB:

If you can't access the single-user mode or use a Live CD or USB, you can reset the root password using the GRUB boot loader menu. This method involves modifying the GRUB boot loader configuration to boot into a root shell.

To reset the root password using GRUB, follow these steps:

• Reboot your system and access the GRUB boot loader menu.
• Select the Linux kernel you want to boot and press the 'e' key.
• Find the line that starts with "linux" and append 'init=/bin/bash' at the end of the line.
• Press 'Ctrl-x' or 'F10' to boot into a root shell.
• Once you're in the root shell, type 'passwd' to change the root password.

Conclusion:

Forgetting the root password can be frustrating, but there are several ways to change it in Linux. The methods mentioned in this article can be used to change the root password, depending on your situation. However, it's important to note that changing the root password can be risky, and you should only do it if you're sure you know what you're doing. It's also important to keep your root password secure to prevent unauthorized access to your system.

 

If you have the root account and access to the command line, you can change the password of any user on a Fedora system, including the root account, by following these steps:

1. Open the terminal: On Fedora, you can open the terminal by pressing "Ctrl + Alt + T" or by searching for "terminal" in the applications menu.

2. Switch to the root account: To switch to the root account, type "su" in the terminal and press Enter. You'll be prompted to enter the root password.

3. Enter the command to change the password: To change the password for a user account, including the root account, type "passwd username" in the terminal, where "username" is the name of the account whose password you want to change. For example, to change the root password, you would type "passwd root".

4. Enter the new password: You'll be prompted to enter the new password twice. Make sure to choose a strong password that includes a combination of letters, numbers, and symbols.

5. Verify the new password: Once you've entered the new password twice, the system will verify that the two passwords match. If they don't match, you'll be prompted to try again.

6. Exit the root account: Once you've changed the password, you can exit the root account by typing "exit" in the terminal.

After following these steps, you should be able to log in to the Fedora system using the new password for the user account you changed. It's important to keep your passwords secure and change them periodically to prevent unauthorized access to your system.

If you have forgotten both the root and normal user passwords on a Linux system, you can still regain access to your system by following these steps:

1. Reboot your system: Start by rebooting your system and accessing the GRUB menu. This is usually done by pressing the "Shift" key during boot-up, or by holding down the "Esc" key on some systems.

2. Edit the GRUB boot options: Once you're in the GRUB menu, select the kernel you want to boot and press the "e" key to edit the boot options. This will allow you to modify the boot parameters.

3. Add the init=/bin/bash option: In the boot options, look for the line that starts with "linux" or "linux16" and add the following text at the end of the line: "init=/bin/bash". This will boot the system into a single-user mode and give you access to a root shell.

4. Remount the root partition: After the system has booted, the root filesystem will be mounted in read-only mode. To make changes to the filesystem, you'll need to remount it in read-write mode. To do this, enter the following command: "mount -o remount,rw /".

5. Reset the password: Once the root filesystem is mounted in read-write mode, you can reset the password for any user account on the system, including the root account. To do this, enter the command "passwd username" where "username" is the name of the user account whose password you want to reset. If you want to reset the root password, enter "passwd root".

6. Reboot the system: After you've reset the password, you can reboot the system by entering the command "reboot". The system should boot up normally and allow you to log in with the new password.

It's important to note that this method should only be used if you have physical access to the system or have permission to access it. It's also important to keep your passwords secure and change them periodically to prevent unauthorized access to your system.
