Forgot notes password
I forgot my notes password from my iPhone 8, is there any way to reset my notes password?

Sorry, but no. Your only option is to keep trying as Apple allows you an infinite amount of tries.
Don't forget your Notes password. Apple doesn't have access to locked notes and can’t help you access them if you forget your password. If you forget your Notes password, resetting the password doesn’t give you access to previously locked notes. Resetting then creating a new Notes password only allows you to lock other notes.
