Two-factor authentication is an essential part of safeguarding customer’s digital privacy. But sometimes at some places, SMS-based two-factor authentication may not work. That doesn’t mean you cannot deliver your sms there, luckily, there are affordable and secure alternatives. Voice 2FA can be used to accomplish the delivery of critical OTP messages to customers who are not able to get the SMS OTP message. This fall-back mechanism is used for user identification and verification.
Let the customers choose from SMS or voice option on website, ads or other touch points.
