Google has been letting Android users set up locked folders in the Photos app for quite some time, giving them the option to keep sensitive images and screenshots safe from prying eyes. Now, the tech giant has started rolling out an update for the app that allows users to back up their locked folders, so they can access files saved in them from any of their devices. In addition, users can now access and set up locked folders — a feature that started as a Pixel exclusive — from the Photos app on iOS and the web. That means users don't even need an Android device to be able to enjoy the feature anymore.
