Users must have a secure screen-lock set Ionic 2 secure storage

I am trying to replace ionic 2 Storage plugin with SecureStorage. But,in the documentation it is said that 'Users must have a secure screen-lock set'. So I am a bit confused. As it is also said that if the security setting is not sufficient then the app developer should inform the user about the security requirements of her app and initialize again after the user has changed the screen-lock settings. I think I don't need a security storage to that extant. So will it be a good idea to move 'Storage' to 'SecureStorage'. If not then what could be an alternative.
