To hide sensitive data, you don't have to go out the Markup tools in the dust. Information technology's nonetheless possible to keep the stuff yous're making disappear never come back once again. And if all else fails, there are third-party solutions.
Tip 1: Add together More Highlighter Layers
The highlighter, which gives you the best wait, can all the same be used to hide content. You just need to employ more layers. Instead of just swiping back and forth over what you lot're trying to hide, lift your finger off the screen before each new swipe.

But swipe iii or iv times, and iOS will believe y'all are trying to hide it and will help y'all out by making information technology impossible to see. Sometimes it just takes two swipes.
In "Passwords" (iOS 14, iOS 15), "Passwords & Accounts" (iOS 12, iOS 13), or "Accounts & Passwords" (iOS 11) in Settings, a screenshot removes the password from the page automatically — a squeamish security characteristic. Simply you lot can too use three or four swipes to obfuscate the username.

For the arrow tool, you can make information technology a thick line instead. For the annotate box, square, and circle, you can fill up it in, so it'southward all a solid colour. Then, yous tin cull a color if the current one isn't what you want. No matter what you do in the prototype editing tools after, in that location'due south no way to reveal what's underneath.
Tip 5: Use a 3rd-Political party App Designed to Obfuscate Personal Info
Meliorate notwithstanding, you could employ professional software to obfuscate individual information and faces. Using Image Scrubber, by developer Everest Pipkin, yous can utilize a heavy-duty marker to hide information, as well equally an first-class blur tool to hide faces.
