It is our pleasure to announce to you that VoiceOTP is now live. You can now deliver those critical One-Time-Passwords over voice. We know how critical OTPs are to some businesses.
We are also aware of the issues around SMS when delivery of instant OTPs are required. But with the new addition to our line of products and services, corporate bodies can now utilize the voice alternatives to get their codes delivered.
VoiceOTP is generally used to verify phone numbers. This is achieved by making a call to the originator’s phone number and playing back a sequence of digits that the originator can input in the initiating app.
Use Cases
VoiceOTP is very useful when timely validation of a phone number is required. This includes but not limited to:
- Transaction authentication for fintech and banks
- App user sign up validation
- Two-factor authentication
- Package delivery authentication
- Spam and bot prevention
