How to Change Notes Password on Mac: Secure Your Notes App in Seconds

I still remember my first locked note on macOS—took me 20 minutes to find where Apple hid the password change option. The interface doesn’t exactly shout about it.

Here’s the thing—this isn’t just changing a password. You’re updating the key that encrypts all your locked notes, and macOS handles it differently than other apps. No terminal commands, no third-party tools.

You’ll have your notes re-locked with the new password in under a minute, and the old one becomes useless immediately. Works across all your Apple devices through iCloud sync.

Between you and me, I’ve seen users lock themselves out by forgetting the new password. Don’t be that person.

Instructions

Here’s the process I use to update the password without losing access to locked notes.

Launch the Notes app from the Dock or Applications folder. I always start by unlocking any existing password-protected notes first—this prevents data loss during the password change. Go to Notes in the menu bar, then select Password.

If you don’t see the Password option, you might not have any locked notes yet. In that case, create a test note and lock it temporarily to enable this menu. The option appears only when at least one note uses password protection.

A dialog box will prompt you to enter the current password. Type it carefully—this is case-sensitive. If you’ve forgotten it, you’ll need to use your macOS user account password to reset locked notes, which will remove the existing lock.

After entering the correct password, click OK. You’ll see the password management screen where you can change or reset the existing password. This step ensures you have the proper authorization to modify security settings.

In the password management window, click Change Password. Enter your current password again, then type the new password twice for verification. Use a strong combination of letters, numbers, and symbols.

Add a password hint—something subtle that jogs your memory but doesn’t give away the answer. Avoid obvious hints like “my birthday” or “pet’s name.” Click Change Password to confirm. Wait until you see the confirmation message that the password has been updated.

Return to your locked notes. You’ll notice they’re still secured with the old password. Open each locked note, enter the new password when prompted, and confirm it works. This step is critical—until you re-authenticate, the old password remains in effect for existing notes.

If a note doesn’t unlock, double-check for typos in the new password. Once all notes are accessible, the change is complete. I recommend testing with one note first to ensure the new password works before updating others.

Tips and Common Mistakes

Here are some key insights to help you change your Notes password smoothly without any hiccups.

The Password Settings Trick: In Step 1, if you don’t see the Password option in the menu bar, it’s likely because you haven’t created any locked notes yet. Create a test note and lock it temporarily—this simple step enables the menu and prevents confusion later. I’ve seen many users overlook this, assuming the option would appear by default.

Case-Sensitivity Warning: When entering your current password in Step 2, remember it’s case-sensitive. If you’ve forgotten it, you’ll need your macOS user account password to reset locked notes, but this will remove the existing lock. Double-check your caps lock key—this is a common mistake that can lock you out temporarily.

Reauthentication Critical: In Step 4, don’t assume the password change applies to existing locked notes immediately. You must manually reopen each note with the new password to update its security. I recommend testing one note first to confirm the new password works before updating all of them.

Password Strength: For Step 3, avoid using obvious sequences like “123456” or “password.” Instead, create a strong combination of letters, numbers, and symbols. A good rule of thumb is to use a passphrase with mixed cases and special characters for better security.
