I'm not terribly keen on providing my actual login to my bank. Ie, adding Betterment asks me for my user/pass Betterment user login (they don't offer 2 factor) - something anyone could then use to login and manage my money there. I see you're using plaid underneath to connect; so giving some assurance that plaid is handling the data flow and sway will not be storing usernames/passwords would be nice (if that is true).
