Hack This Site, unlike Hack The Box, is completely free. It allows you to test and improve your hacking skills as well as serving as a hub for those involved in security. It is not as active or up to date as HTB but the community have done a good job of keeping it alive and going after the founder’s departure.
I would advise you not to get discouraged by the name of this particular challenge. It goes without saying that being unable to do this challenge does not make you an idiot; everyone starts at a point where they would not be able to. Therefore you can ignore the pretext discouraging you from asking for help.
This challenge is the first one under their basic missions category and requires some knowledge of HTML. I will list the steps one by one despite this being a very short mission.
- Right click on the page and select Inspect (Ctrl + Shift + I).
- Look through the code. After the part with the long text, you will see a commented section. Comments in HTML are written between <!– and –>. The comment here tells us the password.
- The password is a mixture of lowercase letters and numbers. Put this password in and you are done!
