Password

There is a hint that was created by you for locked Notes, please use them. If you do not have one then please keep trying various passwords known to you.

There is no way of resetting the Notes password, however, you can create a new password for the new Notes that you would lock or create.

The only option that you have is to keep trying as there is no limit on the number of attempts.

However, you can set a new password for your new notes, but for the old notes, you need to get the old password only.

If you have imported some notes from Old iPhone to the new one then you will have to attach the password to the new Touch ID / Face ID on your new iPhone. At some given time you must have created a password and enabled touch Id / Face ID to the password. Any Notes created thereafter will only use your Touch ID / Face ID. Because of this, it is very likely that you may not recall the password now.

Face ID / Touch IDs are not transferable from one device to another.

There is no way to unlock unless you can recollect the Password. Keep trying there is limit on number of tries.

If you forgot your notes password

You can unlock a note only when you enter the password that it's locked with. If you forgot your 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. But it will let you password protect any notes that you create going forward with the new password. This could lead to you having multiple notes with different passwords.

If you have multiple passwords, you can't tell which password you should use when you look at your notes in the Notes list. When you open a note locked by your old password but enter your current password, you'll see an alert that you entered the wrong password with a hint for your old one. If you then enter the correct old password, you get the option to update that note's password to your current one.
