My Cloud secure?

I bought a new EX4100 and I am new to the WD My Cloud technology, but so far I haven’t been able to find out any type of information about how it works.  Can anyone direct me to any whitepapers or documentation on how the My Cloud app connects to my EX4100 NAS?  I’m a little skeptical on how secure it is.  For example, If I open the My Cloud App and connect to my NAS, then right click on any file and select “Copy Link”, when pasting it, the link is just showing http:// on port 80 (insecure) instead of https:// on port 443 (insecure). 

Thanks.

Have you downloaded the complete user guide for your unit from WD?

I would like the new version of MyCloud.com to have 2-factor authentication to make it that bit more secure.  Obe can hope that it’s implemenbted.
