I canot rest my notes passwords

If you forgot your notes password, Apple can't help you regain access to your locked notes. You can create a new notes password or use your device passcode instead, but this won’t give you access to your old notes.

To reset your notes password:

1. In the Settings app, tap Notes. Then tap Password.
2. Select the Notes account that you want to change, then tap Reset Password.
3. Enter your Apple ID password, then tap OK.
4. Tap Reset Password again.
5. Use your device passcode or enter a new password and password hint. Tap Done.
