Which errors can throw Secure Storage?

I want to control the possible errors that the plugin Secure Storage can throw when an error occurs while creating the storage namespace (create()) but I can not find any info about anywhere.

The only error I had found is one that throws an string saying “Error: Device is not secure” but is it the only one?? How can I be sure if the only problem is that the device does not has any pin or similar? is that THE ONLY error that can happen?
