- Now user are register at that time mobile number and mail id are mandatory and OTP send on mob number as well as on mail id.
- So we should make a configuration for that like :
  - If anyone require only mobile number then we set configuration as mobile number and mail id not mandatory.
  - If anyone require only mail id then we set configuration as mail id and mobile number not mandatory.
  - If anyone require both like mobile number and mail id and we set configuration as both then mobile number &  mail id 
    are mandatory.
