I'll use a call to authority. Amazon uses the email as identity. If it works for them, surely it can't be that bad a decision...

- saurik 14y agoNope, like all other large providers (Facebook, Google, etc.) Amazon allows users to use e-mail addresses to log in, but they are not canonical stores of identity. In fact, Amazon is the most humorous example you could have pulled, because Amazon actually allows multiple accounts with the same e-mail address, and uses the password to differentiate (which is pretty much what jointb86 said, but I doubt if you knew this is the case that his comment was clear).
