I've been trying to sign in at work on my work computer and on my iPhone later tonight using the "Email" portion of two factor that emails you a code to use. It does not send an email. I made many attempts and nothing. Had to go find my 'emergency' one use codes and use one of those. I've lost my Authy password when I switched phones and have not been able to use Authy and depend on the 'email me a code' portion. Just wanted to bring it to your attention.
