No. Email is not a 2nd factor authentication, but the code itself. Email is just how you send the code and also how you alert the user that someone is trying to access his account from a not recognized device. In this case, the code is just an "activation code" (not an authentication code), we can even remove the code and just provide a confirmation link, for instance.

This is not about authenticating users, but authorization. Allowing access only from devices previously approved by the user. Let's say you usually access your bank from your home computer. But for some reason, you need temporary access from a LAN house computer. You probably don't want to allow access from LAN house computers later on.

What I'm proposing is another security layer, which can be used together with 2nd factor authentication.
