I use and prefer Venmo. I dislike PayPal. I have not used Square Cash. I would refuse to use FB Messenger if anyone asked (which no one has).
I have no interest in using an app that by default
broadcasts my transactions to everyone
I haven't seen the default in some time, but it's very simple to change the privileges on a transaction (2 clicks, immediately visible on every transaction), which apply to all your future transactions unless you change it back. Cold comfort, but there you go.
.. it had the audacity of asking for my SSN.
I'm frankly surprised that PayPal
doesn't require a SSN for the same activities... or maybe they do. Venmo help[1] indicates they are required to do so for users with certain volumes (several hundred dollars per week) by the U.S. Treasury. Why would Paypal and other vendors
not have the same requirements?
