If you find your password insecure and wanna change it, you can do that with just type
passwdType your current password, then type your new password, and retype again to confirm.
In case you forgot your password, you can always reset your password with root user. First gain the root access
su -Then, redefine the password for user let say eddie.
passwd eddieWith root user, you can check the details of the password management, regarding when the password is set, and the password duration etc for all user or particular user.
Check user eddie
passwd -S eddieCheck all users
passwd -S -a

When I run “su -”, it prompts for password, that’s the root’s password?
If it’s true, what if we don’t have the root password.. e.g. in Ubuntu default installation. Do we have workarounds?

Sure, you have your own password, in Ubuntu, you uses sudo to gain root access. So, do this
Type in your password, then
Set the password for root.
