@pojntfx wow. 5 years ago, this would have been naive and shortsighted. but now that we have had ample demonstration of exactly why it would have been shortsighted, i din't see how anyone in their right mind could think this acceptable.
I quite like the proposed swiss eID approach. You have verification done by the governemt and granular access to data, e.g. only "at least 16" or "at least 65" (retirement age) without having to reaveal your full identity to the server needing to verify.
