You can just enable otp and scan the code, there is nothing to it

Hi,

This functionality is applicable, if user already exist in keycloak. I want to login fresh user directly through mobile OTP. If user exist it will login and if not exist it will directly login or redirect to keycloak registration page. Can i enable or add this feature in keycloak?

You need to first setup OTP, a code will be stored on the otp app that belongs to a user, so what you want is not possible.

Hello Sanjeev,

could you share the problem briefly?  
Do you have used any 3rd party application for sending OTP?
