 * Hello,
 * I love this plugin – super simple and it works with TML! However, I was wondering
   if there could be a way for users to authenticate their login without an app?
 * It would be rather difficult to ask all the members of my site to install an 
   app on their phone, computer or browser just to authenticate their login.
 * I was wondering if an email could be sent with an authentication code instead,
   since every account has an email attached to it? Is there a way for the plugin
   to do this?

 * Hi,
 * We decided not to implement the sending of codes by email for two reasons:
    1)
   Email delivery is unreliable, and this leads to use frustration. Especially since
   under the standard TOTP protocol (which this plugin uses), one-time codes are
   valid for a short time. 2) For the majority of users, email isn’t a true second
   factor, because WordPress allows them to reset their password via email. So, 
   if both of those go to the same account, then there’s only one factor – access
   to one thing (the email account) gets you everything.

 * David,
 * Thanks for the quick reply.
 * That’s fair enough. Thought I’d ask!
