What is Voice OTP?
Voice OTP, also known as "Voice One-Time Passwords", is a secure and convenient method of two-factor authentication that allows you to verify the identity of users through automated voice calls. Instead of receiving a one-time password through an SMS, users can receive a voice call with a unique one-time password that is valid for a limited period of time. The users then enter this password to confirm their identity. Voice OTP offers several advantages over traditional SMS-based OTPs, such as better security, wider reach, and increased user convenience.
