tom, as well as the new password. You will need to enter the new password twice to confirm it.
If you are changing the password for the root user, you will need to use the
sudo command. For example:

passwd command to change your own password. To do this, you can simply run the
passwd command without specifying a username.
Here are some additional things to keep in mind when changing passwords in Ubuntu:
- The new password must be at least 8 characters long and must contain at least one uppercase letter, one lowercase letter, and one number.
- The new password cannot be the same as the old password.
- You cannot change the password for a user who is currently logged in.
