What is Fallback OTP Authentication?
Fallback OTP authentication is a mechanism in OTP based user authentication where OTP can be sent to the end user via multiple channels. Here is how fallback OTP authentication works:-
STEP 1
- The brand selects priority channels for OTP delivery. The sequence of priority can also change depending on a geography.
- Once Verify Now’s APIs with fallback are integrated with the brand’s application, the mechanism is ready to use.

STEP 2
- When the OTP delivery is triggered, the mechanism starts working where it attempts delivery in order of priority defined by the brand.
- If delivery via first channel of fails, then the system attempts the delivery via the second channel. This goes on till the OTP delivery is succsessful.
