Thanks Greg,
I've set up 2FA and added Screentime. Unless I misunderstand, once logged into the user account you can still click on Passwords, enter the user password, and see all their information.
At least with 3rd party password managers like 1Password, etc,. you need the app password.
For example: My "trusted" Mac repairer always asks for admin password if it's required. So if my MacBook freezes, the service tech needs admin password to diagnose, they now can still open and view Keychain Passwords.
