How do I create a locked, password-protected note category?
To create a new category that is locked, go to the “Categories” screen and tap the “+” button on the right side of the navigation bar at the top of the screen. This will take you to the “New Category” screen. From here, toggle the “Password Locked” switch to the ON setting, and enter a password. To lock an existing category, tap the blue detail disclosure button next to the category you wish to lock. This will take you to the “Edit Category” screen. From here, toggle the “Password Locked” switch to the ON setting, and enter a password.
