As a technical blogger, I can provide a professional explanation on how to reset password on Linux Ubuntu.
Firstly, you need to access the GRUB menu of your system. If your system boots directly into Ubuntu, press and hold the ‘Shift’ key when booting up until the GRUB menu appears.
Once you have accessed the GRUB menu, select the ‘Advanced options for Ubuntu’ and then select the latest kernel version.
Next, select the ‘recovery mode’ option and then select ‘root’ to drop to a root shell prompt.
At the prompt, type in the command ‘mount -o rw,remount/’ which will remount the file system in read-write mode.
Next, type in the command ‘passwd username’ where ‘username’ is the username of the account you want to reset the password for. It will prompt you to enter a new password for the account and confirm it.
Finally, type in the command ‘reboot’ to restart your system and log in with the new password.
It is important to note that this procedure should only be executed by the system administrator or under their supervision to avoid unintended changes or access to sensitive system data.

What to do if you forgot your current password Linux?
Forgetting a password can be frustrating, but there are several ways to recover access to your Linux system. One option is to boot into recovery mode, which allows you to reset the password. Another option is to use a live CD to access the system files and reset the password manually. A third option is to use a tool such as "chntpw" or "ophcrack" to recover the password. Regardless of the method you choose, it’s important to follow best practices for password management to avoid similar issues in the future. This includes using strong, unique passwords, enabling two-factor authentication where available, and storing passwords securely.
How do I find my root password in Ubuntu?
As a technical blogger, I would recommend the following steps to find your root password in Ubuntu:
1. Open the terminal on your Ubuntu machine. You can do this by pressing Ctrl+Alt+T or by searching for the terminal in the Applications menu.
2. Type the following command in the terminal and press Enter:
"`
sudo passwd root
"`
3. You will be prompted to enter your user password. Enter the password and press Enter.
4. Next, you will be asked to enter the new password for the root user. Type in your new password and press Enter.
5. Finally, you will be prompted to re-enter the new password to confirm it. Type in the password again and press Enter.
Once you have completed these steps, you will have set a new root password for your Ubuntu machine. It’s important to note that you should keep your root password safe and secure, as it grants powerful system-level access to your machine.
How do I unlock a user account in Ubuntu?
If a user account is locked in Ubuntu, it means that the account has been locked due to too many failed login attempts. To unlock the user account, you need to log in to Ubuntu as a user with sudo privileges.
After logging in, you can unlock the user account by resetting the password using the following command:
"`sudo passwd -u
Replace "username" with the locked user account’s username. This command will prompt you to enter a new password for the user.
Alternatively, you can unlock the user account by editing the /etc/shadow file directly. Find the line for the locked user and delete the "!" between the first and second colons. Save the file and the user account should now be unlocked.
It’s important to note that unlocking a user account should only be done if you are certain that the account has not been compromised or hacked. If you are unsure or suspect that something malicious may have happened, it’s best to seek assistance from a security professional.
What is the default Linux login password?
Unlike some other operating systems, there is no default login password for Linux. During the installation process, the user is prompted to create a password for the root user account, which is the system administrator account, and it is highly recommended to create a strong and unique password.
Once the installation is complete, the user can create additional user accounts with their respective passwords. It is important to note that Linux is a highly customizable and secure operating system, and the best practice is to change the default passwords regularly and configure secure authentication mechanisms such as two-factor authentication.
What is the default password for Linux?
There is no default password for Linux. When you install Linux on a computer, a user account with administrative privileges is created, and you will be prompted to set a password for that account. It is important to choose a strong and secure password to prevent unauthorized access to your system. In addition, it is recommended to enable additional security features, such as a firewall, to enhance the security of your Linux system. It is also good practice to regularly update your system software to ensure that any potential security vulnerabilities are addressed.
