Drupal 8 and Users

Hello All,

I have given the task of building a drupal 8 site but I am running into some issues. I currently am running drupal 7 on my site so maybe I am just looking in the wrong places for the answer.

Basically I have two questions regarding users.

How do I set users to not be able to change their password through the website? I do not see a permission to set this.

Second is how do I restrict only certain pages to certain users? For instance I’d like non authenticated users to still see directions and parking pages but no internal authenticated pages like news and updates. You used to be able to do this but I can’t see a way to accomplish that in drupal 8.

Any help is much appreciated.

Thank you.
