What is a Voice OTP?

To ensure two-factor authentication, a voice OTP (one-time password) is normally provided via an automated voice call. This procedure can be utilized if the sending of an OTP SMS repeatedly fails. Additionally, customers have the ability to generate an OTP Voice while they are in the midst of verifying the OTP.
