Everyone is digging around IOS 13 trying to find all of the features Apple didn't tell us, but one subtle change to Safari is a big privacy win for all of us.
The "A" letters found within the Safari address bar is an enhanced Reader View, but within that found at the bottom is Website Settings.
Website Settings allows control over what the website has access to on your device. Before IOS 13 we didn't have an option like this.
You can individually control the Camera, Microphone, and Location for every website you visit. Tap one of the options, and you're presented with three options: Ask, Deny, and Allow.
Apple has made it clear that privacy is a big focus on IOS 13. Website Settings is just one feature of many to keep your data secure on your iPhone.
