How to lock or unlock notes on your iPhone, iPad and iPod touch – Apple Support (UK)

• 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 won't give you access to previously locked notes. Resetting and then creating a new Notes password will only allow you to lock other notes.
