send sms and email from one set of code

[Johan van Zyl]

For instance - when somebody logs into (enters UserName and Password and clicks "Request OTP" ) www.medxinfo.co.za an OTP One Time Password must be sent to the user's cell phone and/or email address. Once the user has entered the correct OTP and clicks Login, he will be logged in.
The "Request OTP" button calls another NetWebForm?
This form generates the OTP and sends sms and/or email to user?
Which embed points would be optimal?
