You cannot. OTP stands for One Time Pin and is sent by ICICI
Bank when they sense some kind of change in your login pattern.
This is to identify that it is indeed you and not someone else. For
ex: if I always login from my home computer in India and suddenly
login from Singapore the bank will ask for OTP login because it may
not be you. If you enter the OTP once from Singapore, it wont ask
you for OTP everytime.
