Notes is the default note-taking app for many iPhone, iPad, and Mac users. As of iOS 15, if you use Notes, not only can you jot down casual notes and thoughts on it, but you can also take notes with checklists, images, weblinks, and scanned documents in them.

Since this means you may sometimes also use Apple Notes to store personal/sensitive information in your notes, it’s wise to secure your notes with a password. Apple gives you multiple options to implement this in Notes: you can either do it via a password or use biometrics like Face ID or Touch ID if your device supports them.

Follow along as we walk you through the steps to lock notes on iPhone and iPad.

How to Set Up a Notes Password

To begin with, you first need to set up a password to lock your notes on the Notes app. You have two ways to do this. One, you can set up a password inside the Notes app, or two, you can go into Notes’ Settings and create a password for Notes there.

Steps to Set a Notes Password From the Notes App:

  1. Launch the Notes app.
  2. Open an existing note or click on the new note icon on the bottom-right corner.
  3. Click on the three-dot options menu on the top right.

  6. Toggle the option for Use Face ID or Use Touch ID, depending on your device, to enable biometric unlocking.
  7. Hit Done.

After this, the note on which you carried out these steps will be protected with your Notes password, and you’ll see a padlock icon next to it.

Steps to Set a Notes Password From Settings:

  1. Open Settings.
  2. Scroll down and tap on Notes.

  5. Add a password hint, so you don’t forget your password and get locked out.
  6. Toggle the button for Use Touch ID or Use Face ID to enable it and use it for unlocking your notes.
  7. Hit Done.

Unlike setting up a Notes password in the Notes app, this method won’t lock any of your notes. So if you need to secure a note on the Notes app, you’ll need to follow the instructions in the following section.

Note: If you don’t see the lock option on a note, it could either be because that note is being shared with someone else or it isn’t synced to your iCloud account—and instead, synced to third-party email services like Gmail, Yahoo, etc.

How to Lock Notes on iPhone

  1. Launch Notes and open the note you want to lock.
  2. Click on the More button on the top-right corner.

Keep in mind that when you password-protect a note, its title is still visible on Notes’ home page (page with the entire notes list). So you may want to avoid having confidential information in the title of your notes.

How to Open Locked Notes

When you want to unlock a locked note in Notes, you can do so using the following steps:

  1. Launch the Notes app.
  2. Open the note you want to unlock.

It’s important to note that unlocking a single note will also unlock all your other locked notes. Similarly, re-locking one note will lock all other notes as well.

How to Re-lock Notes on iPhone

After you’re done viewing or editing a note, you can protect it by locking it again. By default, as soon as you exit Notes and lock your iPhone or iPad, all your notes get locked automatically. However, if you wish to re-lock your notes manually, you can do so as follows:

  1. Launch Notes.
  2. Open the note you want to re-lock.
  3. Tap on the lock icon on the top-right corner.
