How to change sudo password in Ubuntu

  • Step 1: Open Ubuntu Command Prompt. We need to use the Ubuntu command line, the terminal, to change the sudo password.
  • Step 2: Login as root user. Only a root user can change their own password.
  • Step 3: Change sudo password via passwd command.
  • Step 4: Exit the root login and then the terminal.

As a user, you can change your own password in a terminal using passwd. You will be asked for the current password and can then enter a new one. On Ubuntu, there is usually no separate password for root. Instead, users with administrative privileges can use sudo to run commands as superuser. To change a password on behalf of a user, first log in or “su” to the “root” account. Then type “passwd user” (where user is the username of the password you are changing). The system will ask you to enter a password. Passwords are not displayed on the screen as you type them. To change it, just try passwd with no arguments or run it via sudo. The password you use for sudo is your own account password, not the root account. sudo is used to give you access to commands that need to be run as root without directly giving you root access.
