Password manager

Hi

I have just installed Brave on my PC. I have imported settings from Chrome - works fine. However it also imported all passwords.

  1. On Chrome I need to write the google password to get access to passwords. In Brave thay are available without password. Why?
  2. How it is even possible to copy all passwords from chrome without asking for password and make them available in Brave?
  3. How to turn off the password manager? I can only disable saving new passwords. I want to disable the manager and delete all passwords. How?
