Wow. These things have become so common, the Quora hack didn't even make it 
into my newsfeed.

If you need person-to-person private conversation, why not email with 
PGP/GPG ? 

You could also use GPG to convert messages to text and insert it into a 
tiddler. Then any public exposure would be irrelevant.

PGP has been around since almost the beginning. It's had slow adoption 
because of the fiddly steps needed to set it up on both ends of a 
conversation. Something like it should be the default -- the way https is 
becoming the default.

You mentioned Bob can run scripts for you. I can imagine invoking a script 
that converts tiddler text to gpg and turns it into a tiddler.

2FA as commonly implemented with SMS turns out to be no panacea -- cell 
phone numbers can be hijacked. Using a FIDO device might be better, but is 
not widely supported yet. None of this 2FA does any good if the main 
database, as in the case of Quora, is hacked.
