I forgot my notes password.

Hello maria-sara,

From what you've shared it appears that your note is locked, and we'd like to point you towards some helpful information. Get started here: How to lock notes on your iPhone, iPad, and iPod touch

Please note, if you forgot the password, Apple can't help you regain access to your locked notes. You can create a new password, but this won’t give you access to your old notes.

Take care!

do you still have your old phone and haven't erased it.

If not, then if you don't know your password you will not be able to recover the notes.
