Will secure storage be created if configuration option is NOT passed?

[vigneshvpai]

I have the following code.
import createSensitiveStorage from 'redux-persist-sensitive-storage';
const storage = createSensitiveStorage();

Note that I haven't passed any configuration options to the createSensitiveStorage() function.
What happens if I don't pass the configuration? Will I still get secured storage by default or do I get an unsecured one?
