Can we lock/password protect pages in Notion?

Hi, I'm using Notion for sometime now. It's usually for my notes taking in the most simplest way. I just open new pages & take notes. While I understand there are other ways to also use notion some use cases that come across my mind is financial planning, daily journals etc. which I can do over Notion but a constant itching & thought that if somebody get access to my Notion, they'll know it all. I'm little conservative with my thoughts & want privacy with many of my things. Is there a way we can restrict the access to pages by any password protection in the Notion ?
