Html[password login]

Question

Hi, I built my own Website with html. On my Website you have to login, the login is on the „index.html“ site, but when there is a way to get acces to the other sites without login, when you write example:

domain.de/othersite.html

Is there a way to block it?
Normaly you only weite example: domain.de which is the index but withe the trick i told you can get acces is there any way to block?
