How to change your My Eyes Only password if you forgot It

Creating a custom password for locked notes can provide additional security, but if you forget the password, you may lose access to your locked notes.

You use your custom password to access your locked notes on all devices where you’re signed in with the same Apple ID. If you have more than one iCloud account or an “On my iPhone” account, you can set a different custom password for each account.

To access notes locked with a custom password, you must be using iOS 9.3, iPadOS 13, OS X 10.11.4, or later. On devices with an earlier version of the OS, you won’t see the notes.

1. Go to Settings

   
    > Notes > Password.

2. If you have multiple accounts, choose the account you want to set a password for.

3. Tap Use Custom Password.

4. For added convenience, you can also turn on Face ID or Touch ID.

   Don’t rely on Face ID or Touch ID as the only means of unlocking your notes. If you update your Face ID or Touch ID settings, or want to change your Notes password, you have to reenter your Notes password.

Important: If you forget your custom password, and you can’t use Face ID or Touch ID to access your locked notes, Apple can’t help you regain access to those notes.

You can reset your custom password, but this doesn’t give you access to previously locked notes. The new custom password applies to all notes you lock from now on. Go to Settings > Notes > Password > Reset Password.
