> Logging into a website: rather than typing your password into a potentially unsafe website, you can simply send a proof that you “know your password”.
Authenticating your identity: rather than giving your mother’s maiden name over the phone to a random, bank call center agent, you can simply send a proof (a cryptographic fingerprint), that you are who you say you are.
These examples tipped me off. Can someone help me understand how it is safe. Say one can send the exact cryptographic fingerprint and impersonate me. How is this anything better than me just sending password to authenticate?
I am really not sure why is it only fb whose name pops up in media. IMO, this update will affect entire advertising industry. Be it giants like Google, Tradedesk, Amazon etc. In the end it is loss to the advertisers as lack of data will be hampering their measurements and targeting. Not sure if for internet platforms it matters. Will this be good for businesses in streaming TV like roku, apple, firetv?
