A hidden album on an iPhone is a photo album that is not visible in the Photos app. This can be useful for storing private or sensitive photos that you don’t want to be seen by others. To create a hidden album, open the Photos app and tap on the Albums tab. Then, tap on the + button in the top-left corner and select New Hidden Album.
Hidden albums are a great way to keep your private photos safe and secure. They are not visible in the main Photos app, and they can only be accessed by entering a passcode. This makes them a great place to store photos that you don’t want to be seen by others, such as nude photos, financial documents, or medical records.
