title: Multi Factor Authentication WSO2
body: <p>I am trying to achieve MFA in WSO2. I made changes as per the below link but nothing worked,
  <a href="https://docs.wso2.com/display/IS510/Multi-factor+Authentication+using+FIDO" rel="nofollow">https://docs.wso2.com/display/IS510/Multi-factor+Authentication+using+FIDO</a></p>
  
  <p>I am a bit confused, do we need a physical U2F device to achieve this MFA?
  Are there any other multi factor authentication methods/tutorials available for WSO2?</p>
