In iOS 16, Apple made the Hidden album in the Photos app more secure by locking it with Face ID, Touch ID, or the device’s passcode.
This means that when you open the hidden album, you have to authenticate with your face or fingerprint so that no one but you can access the pictures you send to that album.
iOS 16: Steps to Lock Hidden Photo Album on iPhone
In the “Settings” app, open the “Privacy” section and change your default privacy settings.
Scroll down and look for the “Photos” application on your phone.
To use Face ID or Touch ID on your iPhone, first make sure the toggle button adjacent to it is enabled. ..
After deleting a folder and photos, a little lock icon will now be visible next to the recently deleted folder and the hidden photo album.
Final Words
If you have an iPhone that is running iOS 16, you can add a Hidden album to the Photographs app so that others cannot see your photos without your permission. This hidden album can be used to keep photos from others, or to protect yourself from potential embarrassment.
