Apple doesn't have an official method for individually locking sensitive apps like Photos with a passcode, but luckily there's a workaround that was introduced in iOS 12 with Screen Time.

If you really want to make sure one of your apps is inaccessible, you can use Apple's App Limits feature to do so. Here's how:

  1. Open up the Settings app.
  2. Choose "Screen Time."
  3. Make sure Screen Time is enabled and a Screen Time passcode is set.
  4. Tap on "Devices" in the upper left corner and select your current device. If you don't have multiple devices, just tap on the name of your device at the top.
  5. Choose an app you want to lock and tap it. If the app you want isn't listed, choose any app. It's just a gateway to get to deeper settings. setapplimit
  6. Tap "Add Limit."
  7. From here, tap "Edit Apps" and add all the other apps that you might want to lock. It gives you a full dropdown of all your apps.

After you've selected all of the apps that you want to be locked, use the timer interface at the top of the display to select a short period of time, like a minute, and then tap "Add."

The new App Limit will effectively lock up your selected apps, and if you attempt to tap on one of these locked apps, you will be required to input your Screen Time passcode.

How to Use a Locked App

Once you have App Limits in place to lock apps you want to be inaccessible, you can tap on "Ask for More Time" to access the app. You'll need to put in your passcode, and then once you do, you can unlock it for 15 minutes, an hour, or the rest of the day. There's no way to immediately lock it again after approving it for 15 minutes without redoing the entire App Limit setup, so keep that in mind.

Limitations

You can passcode lock any app on your phone except for the Phone app. There is no option to turn off access to the Phone app at all. For apps like Messages or FaceTime, you need to edit the "Always Allowed" section of Screen Time to remove them for the limit to be enabled.

You can disable access to Messages and ‌FaceTime‌, but you might not want to. When access to Messages is disabled via App Limits, devices using iCloud for Screen Time are not able to send or receive messages during downtime. You're also not able to see notifications for apps that are locked, so keep that in mind when locking down social networking apps.

An Alternate Locking Method

If you want to lock up most or all of your apps, you can follow these steps:

  1. Open the Settings app.Choose "Screen Time."
  2. Make sure Screen Time is enabled and a passcode is set.
  3. Select "App Limits."
  4. Tap "Add Limit."
  5. Select "All Apps & Categories." applimitsallapps
  6. Choose a short period of time from the timer interface, such as a minute or two.
  7. Tap "Add."

Choosing "All Apps & Categories" locks all of the apps on your iPhone except for a few. You can narrow that down a bit by selecting just a category of apps to lock, such as "Social Networking," and you can unlock individual apps by going to "Always Allowed" in the main Screen Time interface, selecting "All Apps & Categories" and unchecking, the apps that you want to make accessible.

Nice. But Apple can simplify this process by giving us the ability to officially lock our apps.

Don't forget your Screen Time passcode, which is not the same as your Lock Screen passcode.

It's pretty hard to recover from a lost Screen Time passcode, so add it to your password manager. You DO have a password manager, right?

I mean that makes sense, but we can play the what if game all day long with 58385 scenarios. Other than photos, I don't see why you would need apps protected?
Photos aside... not wanting people to be able to access your Messages. Not wanting people to have access to your dating apps. Not wanting people to be able to post from your social media pages. Not wanting people to mess with HomeKit stuff (lights, locks, alarms, garage doors etc). Not wanting people to go through your browsing history. Extra protection for banking apps (most/all of which already have a layer of security, but another layer would be more comforting). Having extra security on private things if your phone was stolen unlocked. There are countless ways this would be useful for people.

I understand a phone lock would solve a lot of these, but that's not always possible - especially in the case of children using their parents' phone/s throughout the day. This seems like such a simple task for them, I don't understand why they wouldn't just make it an option.

Doesn’t work for me. You still have to use every time limited app for at least one minute every day before it is locked for the rest of the day. After three days this gets super annoying.
