Flags and user and root ??

I am newbie… i was wondering do you need to submit the flag to own user and root. DO ALL challenges have these flags?

Every challenge has a flag in the format HTB{fl4g h3r3}. The boxes are different, and have a user flag and a root flag, which will look like 8d14a467e19f34393b159ba082c003e7. Submitting the user one gets you the points for user, the root for root points.

how to enter the flag hash on the machines also my hash is always incorect
