Which Notes Can't Be Locked?

While you can use your Notes app to lock notes that contain photos, you can't currently lock notes with the following types of content:

  • Video
  • Audio
  • PDF or file attachments.

If you are trying to lock a note with any of these, that's your problem. If you don't need the incompatible data in the note, delete it and lock your note without it. However, if you want to lock those files, there are some other options. For more ways to keep your content private, check out our Free Tip of the Day.

Other Ways to Lock Your Content

Since the locking options in Notes are imperfect, you might want to look elsewhere for locking private content on the iPhone. Two strong options are:

  • Add photos and videos to the Hidden folder in your Photos app. Your Photos app has a built-in hidden folder that lets you add photos and videos you want to keep out of your main camera roll. It's useful if you want to keep people from seeing certain things while flicking too far left or right, but it doesn't have a lock, so someone could easily open it if they have access to your camera roll.
  • Use a third-party app to lock your content. Sometimes you need to go outside of what Apple has to offer. There are a lot of third-party apps that promise security, but many of them cost money so it can be hard to know what to trust. Luckily, we have some suggestions of best apps to hide photos and videos on your iPhone. You're sure to find something to suit your needs, so rest easy!
