I'm glad you have a portable device which you can use to access your email. Not every user does.
But you're right. Please use and implement candy security structures.
>How is it not helping? Now you have all your accounts requiring two-factor auth to log in, rather than just some of them. You also only have one server to secure, which will presumably be run by people whose sole job is to secure that server.
Yes, you are left with only one server to secure, and yes it is most likely run by people who are good at it. But this is exactly why it's a good example of candy security: As soon as you get past the first wall, there is nothing else stopping you from getting access to everything. And you can't really presume all users will have double auth activated, nor that they will be as cautious with that single set of credentials will be.
This is the question I'd like you to address: How is it less secure than what we have now?
