How to Lock Notes on iOS and Mac
Locked Notes
Whether you're an iOS or macOS user, you can lock individual notes using your passcode, password, Face ID, or Touch ID. It's a great way to ensure that your sensitive data stays secure and private.
How to Reset a Forgotten Notes Password
If you have locked some of your notes and forgotten your password, you can reset it quickly with just a few taps. But keep in mind that this will only unlock the notes that you locked with your old password; those protected using a different password will remain locked.
Reset a Password*
In the Settings app, tap Notes and select Reset Password from the pop-up menu. Enter your old password, new password, and a hint in the Password and Verify fields. If you want to use Face ID or Touch ID to verify, toggle on Use Face ID or Turn on Touch ID.
