I am having the same issue.  We have changed over to a VOIP telephone system and I am not getting the phone call for the 2 part verification.  I can not sign into the account because I am not getting the 2 part verification.  I get the email with a code the code but then it still wants to send the 2nd part to my phone and I don't get it and I don't have a cell phone tied to the account to get a text. And I am still waiting for the phone call from them I was supposed to get 2 hours ago.
