My Passport Ultra will not back up Facebook

When I try to back up to My Passport Ultra, I get the message “Facebook has detected WD Discovery isn’t using a secure connection to transfer information. Until WD Discovery updates its security settings, you won’t be able to use Facebook to log into it.” There is no problem backing up Google Drive, Dropbox, or OneDrive. It is just Facebook that refuses to back up.

It isn’t even clear what the message is referring to when it says "WD Discovery isn’t using a secure connection. The drive has a security password on it. My wireless connection is secure. Where are the “security settings” that need to be updated?

I have searched the My Passport Ultra manual, the Internet, and WD support for a solution to the problem and have not found it. I emailed WD support directly and received no response. I could really use some help.
