I see and agree with the privacy concerns however I'm trying to judge whether my target demo values ease-of-use over friction that comes from managing passwords. The demo I'm looking at is quite broad so I'm trying to plan for the lowest common denominator...questioning my early adopters is definitely part of the plan but I'm trying to pre-empt some potential technical complexity in the beginning.
