2 factor authentication

Hello folks,

Would like to know whether any one of you worked on SAML 2 factor authentication.

Has someone done implementation on 2 factor authentication using SMS (OTP)? If so please share the sample code or pointers from which I get more details.
Any help on this would be great help for us.

Thanks & Regards
Deepak Prajapati
