How do I turn off needing to put in my password for App updates?

Once my kids have gotten my password to install an app, how do i turn off needing to put in my app every time there’s an update.

Do i want to put in my PW so that my 12 year old can’t download Tinder? Yes.

Do i want to put in my password every time Roblox comes out with an update (which is practically daily)? No. That would be stupid.
