Sudo Users

Ubuntu users highly recommend performing system tasks by granting access to the tool name sudo. To organize and run a program Sudo is quite essential. The initial user created by Ubuntu is already a member of the study group. If you want to access another user, add the user to the sudo:

usermod -AG sudo username

To elevate temporary root users privileges, run the command prefix sudo:

sudo some-command

The first time you use Sudo, you will be prompted to enter the password. If you want to run the command with sudo without entering the password, you must edit the sudoers file.

 sudo visudo

It will open the / etc/ sudoers file with your desired command line to edit. Copy the following given line by replacing username with your desire username:

Username ALL=(ALL) NOPASSWD: ALL

Ubuntu Default Password

Ubuntu is both the username and the password. A username and password are specified to Ubuntu during the installation. You can't find any default login password of Ubuntu or any operating system. By default, the Ubuntu root account password is locked in Ubuntu.

If you enabled the Ubuntu root user in Ubuntu, you have to disable it, and you have to perform a few minor changes. Set the Ubuntu root password to expire. To disable the root accounts, use the following command:

Sudo passwd -1 root

Advantages and Disadvantages of Ubuntu

Here you can find the pros and cons of using Ubuntu leaving root logins disabled by default, includes:

• People often forget their login passwords occasionally (the root password).

• It avoids the access of "I can do anything" login by default. It will prompt for a password earlier; the changes can happen!

• Sudo adds a log access of the command(s) run (in /var/log/auth.log). In case you were in trouble, you can go to the authorities and run.

• Every cracker trying to brute-force their manner in on a server will know it has an account named root and could try that first.

• What they do not know is the usernames of your other users. Due to the fact that the root account password is locked, this attack doesn't pose any threat at all as there may be no password to crack or guess inside the first location.

• Allows easy transfer of admin rights by adding or removing users. When you use only one Ubuntu root password, you could change the root password if you forgot.

• Sudo may be set up with a safety policy.

This Ubuntu root account password should not be shared with all people who need to perform the desktop's administrative task(s).

Automatically the authentication expires after some time (you can also set the time duration). So if you walk away or leave your desktop a few times from the terminal after running commands as root using sudo, you will not be leaving a root terminal open indefinitely.

Conclusion 

The root user password is disabled, but that does not mean your Ubuntu root account has been removed. Logging in as the root user is impossible because no passwords have been set for the root account.

While entering the password, make sure to use different numerals, special characters, or letters to make a strong password. Hence, setting up a unique combination of root passwords is crucial to maintaining your account's security.

You can also add special characters to your password. Add up to at least 16 characters with upper, lowercase letters, and numbers. It is how we can change the default root password.
