Photos has long provided a hidden album you could use to hold images you wanted to keep a little more private. Until this year, however, it was security through obscurity: anyone who knew to reveal the album in Settings > Photos on an iPhone or iPad or by choosing View > Show Hidden Album on the Mac could see its contents.
Now you can protect it—and the Recently Deleted album—with Face ID or Touch ID on an iPhone or iPad, or Touch ID or your password on a Mac.
You can enable this feature in iOS 16 or iPadOS 16 using Settings > Photos > Use Face ID/Touch ID;
in macOS 13 Ventura, choose Photos > Settings > General and select “Use Touch ID or password.”
From then on, opening those albums will require authentication.
