One Time Passwords
Use OTP authentication through SMS or Voice to secure your data, accounts, and user transactions through Two-Factor Authentication API.
What is an OTP (One Time Password)?
Just a password as security isn’t secure enough anymore. Protect your customers from unauthorized accesses with Two Factor Authentication (2FA) or a One Time Password (OTP).
A One Time Password is a series of characters or numbers that are automatically generated for a single login attempt. One Time Passwords can be sent through SMS or Voice to the user's phone and are used to protect web-based services, private information, and data.
An OTP adds an additional layer of security to your application. Users no longer have to log in solely with their password, but they also need to identify via an OTP through SMS or Voice.

One Time Passwords through Voice
An alternative to SMS is Voice. With Voice, the spoken password is received as a phone call on the user's cell phone. You can also use Voice as a backup if your SMS message is not delivered.
