– open a terminal an login as root ( if the system permits loging in as root )
or
– open a terminal, login with your account and type “su” to become root.
Enter the ( old ) root password to login
then type “passwd” and it will prompt you for a new password.

Changing password for root
Enter the new password (minimum of 5, maximum of 127 characters)
Please use a combination of upper and lower case letters and numbers.
