mac how to find "root" (superuser) password

[regretderp]

I tried to change my username of my user and I accidentally clicked cancel instead of confirm, so i only have guest and standard users. Now I'm trying to give admin privileges back to my standard user and I need the password to the "superuser/root" user. Directory Utility and Terminal shows the password as a single character, shown as a *, and Directory Utility shows * with a data value of "2a".

On a mac? Boot to the recovery partition.

I believe it's "restart and hold option when it's starting up"

i've just entered in the recovery partition and entered in my wifi password, what to do next

 

update: i followed the on screen instructions and i landed back on my standard user account

update (1): i rebooted it back onto the recovery partition and i just entered in my wifi password and its telling my to click on Macintosh HD

Pretty sure there's a "reset password" option somewhere in the recovery menu. You may need installation media instead. I'm unsure, haven't had to reset a password in years.
