I am not able to access’my locked notes bcz I forgot my password of that notes

When you created the password for the locked notes, you were given the option to create a hint to help you remember the password. If you didn't take advantage of that opportunity, you won't be able to ever unlock the notes unless you can remember the password, as KiltedTim has correctly informed you. Anytime you create a password that is important to be able to recall, you should note it down somewhere where you can recall it if you need it. Otherwise, what would be the value of locking something if it could be easily bypassed?

How come I will never be able to recover, it it is in my iPhone with my Apple ID I wrote those notes and I set the password and I forgot it because I’m a human, and I can Proved that those notes are mine so how I can’t recover them that doesn’t make sense, like you are protecting my things from me??!!

come on there gotta be way to recover it!!!!

Because the lock password is encrypted on your phone and cannot be found, removed, replaced or any other means other than entering the correct password. As I mentioned, if the notes were important enough to lock, it was important enough for you to note the password or create a hint when you had the opportunity to create one. It matters not at all that you own your phone.

This is how it is and there is no other solution, period.

There is no way to recover the password for notes. You will need to remember it or unfortunately you will not be able to access them.

why not ? I need this notes open but forgot the password anyway i can change it with my face-id ? or at least use my password.

Because it doesn't exist anywhere other than in your head. It's used as the encryption key for the notes.

If you can't remember it, you can't decrypt the notes to read them.
