How to set password for root in ubuntu?

@margarett 

To set a password for the root user in Ubuntu, you will first need to enable the root user account. To do this, open a terminal window and run the following command:

1

sudo passwd root

This will prompt you to enter and confirm a new password for the root user. Once you have entered the password, the root user account will be enabled and you can use it to log in to your Ubuntu system.

You can then use the su command to switch to the root user account and run commands with root privileges. For example, to switch to the root user account, you would run the following command:

1

su -

You will be prompted to enter the password for the root user, and once you have entered it correctly, you will be logged in to the root user account and can run commands with root privileges.

Keep in mind that it is generally not recommended to use the root user account on a regular basis, as it can be a security risk. It is better to use a regular user account with sudo privileges to run commands that require root privileges.

While it is possible to enable and set a password for the root user in Ubuntu, it is not recommended due to security risks. Instead, it is recommended to use the sudo command to run administrative tasks with elevated privileges.

If you need to perform administrative tasks as a regular user, you can use the sudo command to temporarily acquire root privileges. To use sudo, you must be a member of the sudo group or have sudo privileges enabled for your user account.

To run a command with sudo privileges, prefix the command with "sudo" and enter your own password when prompted. For example:

sudo apt update

This will run the "apt update" command with root privileges. You will only be prompted for your password the first time you use sudo within a certain timeframe (usually 15 minutes).

If you still prefer enabling the root account and setting a password for it, you can follow the steps mentioned earlier. However, it is strongly recommended to exercise caution and only enable the root account if absolutely necessary.
