title: OAuthCard & Magic Number in MS Teams
body: <p>I'm using OAuthCard &amp; AAD v1 in Bot Framework v3, and have deployed my bot to MS Teams (desktop &amp; browser). It requires me to input the magic number to finish authentication. I had thought OAuthCard would no long require magic numbers. Am I missing something, or does anyone know what channels still require magic numbers to be entered? </p>
  
  <p>I'm using the sample AAD v1 Bot on <a href="https://github.com/Microsoft/BotBuilder/tree/master/CSharp/Samples/AadV1Bot" rel="nofollow noreferrer">Github</a></p>
