Temporarily switch to root

Ubuntu users are encouraged to perform system administration tasks by granting sudo privileges to regular users. Sudo allows authorized users to run programs as another user, usually the root user.

The early users the Ubuntu installer created were already members of the sudo group. Most likely the user you are logged in with is currently granted administrative privileges.

To temporarily increase the privilege to root, run the command prefixed with sudo:

sudo nama_perintah

The first time you use sudo in a session, it will ask you to enter the user password.

To temporarily switch to the root account in the current login session, you can use the command sudo suor sudo -iand enter the user’s password:

Changing the Root Password in Ubuntu

Ubuntu’s root user is disabled, but that doesn’t mean that the root account has been deleted. Logging in as root is not possible because no password has been set for the root account.

If for some reason, you need to activate the root account all you need to do is set a password for the root user. In Ubuntu, you can set or change a user account password with commands passwd.

To change the root password in Ubuntu, run the following command as user sudo:

sudo passwd root

You will be asked to enter and confirm the new root password.

When setting a password, make sure you use a unique and strong password. Having a strong password is the most important aspect of your account security. Often a strong password has at least 8 characters, which contains at least one uppercase letter, one lowercase letter, one number, and one symbol character.

Passwords are not displayed on the screen when you type them.
