title: Two Factor Authentication via Email in Twilio
body: <p>By looking over the DOCS of Twilio, the Twilio has started two factor authentication codes to be sent in Email too. But I cannot find any implementation of this using Authy API.</p>
  
  <p>I am using Python, and currently sending SMS based 2FA codes to phones using below code:</p>
  
  <pre><code>from authy.api import AuthyApiClient
  AuthyApiClient(AUTH_SECRET_KEY).phones.verification_start(PHONE_NUMBER, COUNTRY_CODE)
  </code></pre>
  
  <p>I want to give flexibility to my user, to either OPT for SMS or EMail based OTP, not both. I have already integrated my SendGrid Account to Twilio. Any help on code part, I didn't find any implemented code using the above code.</p>
