Part 1. What Are Notes with Password on Your iPhone

To protect your important notes on iPhone or iPad, Apple provides two options to lock your notes on iOS 16 or later: set a password or use your iPhone passcode with your iCloud accounts logged in. No matter which you choose, you can selectively enable Touch ID or Face ID to access your notes more conveniently. When you forget your iPhone/iPad passcode or Notes password, you can unlock your notes with them.

You don't have to set a specific password if you use your iPhone passcode to lock your notes. If you use multiple Apple devices, use the passcode or iCloud login password to access those notes. If you change your iPhone passcode, you can use the new one to unlock all your notes.

When you set a unique password for your notes, if you forget it or can't access it with Touch ID or Face ID because you have updated them, even Apple can't access the locked notes. You can reset this password and use the new password to encrypt new notes, but locked notes with the old password won't be unlocked until you enter the right old password. Therefore, it is highly recommended that you remember the password or set a clear hint for it.

For iOS later than 9.3 and earlier than iOS 16, you can't use your iPhone passcode to lock notes – you have to set a specific password. Remember the same issues as iOS 16 when setting a password for notes.

Part 2. How to Lock Notes Using iPhone Passcode/Set a Password

When you set a password for notes for the first time, you can go to the Settings app and complete the steps. If you choose to set a password, remember that Apple Notes only allows users to set one password for all notes you want to lock. Turn on the iCloud Keychain first to lock notes with the iPhone passcode.

If you choose Create Password, ensure the Use Custom Password option is checked and read Step 3.
