I would love this browser experience when visiting a new website: "<name of site> would like to create an account for you with your (previously vetted) profile data and email. Shall I create a random password and save it to your secure Google account before agreeing?" And then hitting "Yes" does just that, and I'm in. The same workflow could be used for shipping info and CC info.
